This is incredibly poetic. In some way you expect the smoother (higher beat) watches to 'get there quicker', but in reality they all take the same time to get there. For a race (no pun intended) so focused these days on achievement and success -at speed-, there's a lesson here. We all get there! Even if it's not as smoothly as the next person.
That was pretty deep, well done 👍👍
There are a lot of quartz movements with higher beat rates. My favorite is currently the bulova lunar pilot
Honestly, if more quartz watches implemented the smooth sweep second-hand, I would happily buy them without question, despite my preference for automatics.
Haha so true 😃
a week ago, I've seen Casio analog quartz watch with sweeping second hand
I bought a Galaxy watch and have limitless dials to choose from [Sinn 104 my fave ]and each one is as accurate as you can get with a beautiful sweeping seconds hand ,
@@Dave062YT too bad its battery won't hold more than few days, and it doesn't do ticking
@@MegaZidzid Not a problem at all to charge it for an hr every 3 days and u can get them to tick if you really want that .I'm a long time watch collector and since bought this 6 months ago really havent wanted anything else
0:30 1 beat per second
01:03 5 beats per second
02:03 6 beats per second
03:03 8 beats per second
04:03 10 beats per second
05:03 16 beats per second
07:00 all watches compared on screen
Should just be like this
Price tag:
Moneyyy to MONEEY to Take my kidney
(Ain't got no money but need the watch )
The hero that we needed
Fe many Russian watches have 19.800 bph...which is 5.5 beats per second.
Let's face it: the only reason they use beats per hour rather than per second is to sound fancier.
Never was a fan of Quartz watches just because of their 3600 movements. Didn’t know that there are ones out there with higher frequencies. Thanks for that video! I just learned a lot from you! :)
I love that you mentioned benefit of longer service interval. Good job.
+muffemod thanks 😊
And for really high BPH, a Bulova Accutron is the pinnacle: 1296000 BPH, 360/second - directly driven by a tuning fork.
Ah, if only I had one.❤️
I'm a longtime Bulova fan, but I've never owned an actual tuning fork driven model.
Ahh, you seem to have forgotten Mr Hetzel then went to Omega and developed the 720hz Megasonic! :)
I absolutely love mine, its silky smooth.
Got a few 214 and 218s too.
They are tricky but fun to work on.
Yes, I love my Omega with the Accutron movement. That perfectly smooth second hand movement is mouth watering.
I turned this on to kill some time but it turned out to be really interesting! Nice video.
+spookyspoots thanks :)
Spring drive!!!!
Aunchient Pistol it’s more a machenical than a Quartz because iT has a self-winding rotor......don’t see that on your avarage Quartz piece -_-
No it isn't. It is mechanical with a built-in timing machine that - in fact - is quartz. But it doesn't change the fact that the movement itself is mechanical.
Also magnetic
Steven: So are the brakes of a streetcar. But that doesn't make it a maglev train, does it?
In other words, spring drive is mechanical movement, quartz is there for the mechanical movement to check with the quartz to see if it is keeping accurate time.
Grand Seiko has the smoothest sweeping movement. A good informative video.
+nizam mohd yup, spring drive has no real competition 😊
Grand Seiko's is the actual meaning of smooth sweeping. And it is deadly accurate. I have had the luck to handle GS and I can say it is a pleasure to watch (no pun), to look at and to handle. Exceptional quality, for half the price of a Rolex. Owning a GS should be a human right.
+Isse Al O haha I would like that
Watch Geek Omega's Co-axial escapement has no real competition.
Bulova's UHF is just as smooth.
Just to think, pre quarts, "dead seconds" or 3600bph was considered one of the most difficult beat rates in nautical timekeeping.
Appreciate how you timed the seconds hand with all the watches at the end to be in the same location on the dial. I watch reviews where they always compare two watches or more and each watch is timed differently. Great job!
Very educational video. Great job!
+GreatAffordableWatches thanks 😊
All the Accutrons came with tuning fork technology that gave them a continuous sweep, accurate to within + or - 2 seconds per day.
Nick Konig god i wish they still made those movements
+Floyd Burkett I wish that too, they could at least issue a historic line of a few limited edition models with the REAL Accutron movement
Wow, just beautifully produced and written. I have the Bulova Moon Watch and always run the chrono, even though I know that it will tax the battery. However it's so much fun to look at. So smooth and accurate.
Very interesting to see those side by side. I also have an old Timex that runs at 4 BPS / 14,400 BPH.
Now I'm seeing some of you older videos. This one is incredible. And Precisionist movement is marvelous. Thanks a lot
Crisis that King Seiko is amazing, absolutely beautiful!
Hey man, I've been enjoying your videos and comments around WatchTube for some time. I really appreciated the extra effort you took to "pass the baton" between the second hands during the shot after shot comparison of these watches beat rates. You even sync'd the chrono to the face seconds on the Lunar Pilot! Great stuff, keep it up :)
Haha thanks 😁👍
Cool video. I think 8bps would be a perfect combination for accuracy and maintainability.
Some brands/models toward the higher end used 18,000 BPH Hand winding movements still. Like Panerai with the UNITAS 6497 and Chezard caliber 7400
+Neuro yup, which why lower beat doesn't mean lower grade of movement 😊
Excellent video. It's very nice to understand a low beat nd a hi beat automatic watch. I love watches nd I have a collection, but now I'll keep it in my mind because beat rate tell us the worth nd quality of mechanical watch. Thank you. Very Respect from Pakistan 👍❤️
That moment when you look at your watch and the time is synced 😎
Interesting . Thank you . I have a Bulova automatic from 1949 . It looks like it is going like the Sieko . 6 beats per sec . It is 17 joules .
Watch Geek:"If you want high beats, you gotta go back to quartz"
Zenith Defy Inventor: "Let us introduce ourselves" *goes 18hz*
The last moments are very satisfying to watch! 😃
"I will shut up for now, thank you for watching. Bye". 06:35
I believe the Bulova on the video is a quartz watch (Bulova Moon watch), which means that regardless of the higher beat rate, it will probably need less servicing than other mechanical watches, probably even less than lower beat mechanical watches (I'm going on a limb here). Quartz are battery powered, which means that they have less moving parts (no balance spring or wheel) which means less maintenance needed. However, the rule mentioned in the video still remains true if we're talking solely about mechanical watches.
I personally like the 1beat per sec, i just like hearing each second when it's very silent.
Thanks for this video ! I can finally see the difference between each movements
Who the hell gave this a thumbs down? This is a great video. Thanks!
+Private Parts Haha thanks :)
Private Parts admit it matE, *you* thumbed down the video
Haha
Enlighten me about the wrongs in the video
Thanks for the comparison video. As a beginner to the watch world, it's very helpful.
I'm one of the rare few who actually prefer the movement of a quartz seconds hand. To me, nothing is better than a high quality quartz ticking perfectly in line with the markers, nailing every one. Something like The Citizen line is perfect.
Well explained & very well put together.
Thank you for taking the time to do this.
Thanks for watching and for the kind words 😊👍
There are also the Bulova Accutron with electronic tuning fork (300 Hz or 360 Hz), with a real sweeping second hand.
Bulova 262 khz runs at 16 beats per second from what I have read about the movement and seems to be accurate according to the UHF Bulovas I own. I have several that have yet to go out of synch with atomic time over the past 5 months. I think, in my opinion, that they’re superior to the higher end mechanicals I own and really enjoyable to watch. Of course Bulova does make some really unattractive train wrecks, but they’ve got great history and some real innovation under their belt.
I have a bulova accutron from 1972 tuning fork model unsure if it beats 360 or 180 a second still less than 7 seconds a month, omega made 300hz models and Citizen had a licences agreement with bulova to produce them. Unfortunately quartz killed them
A year after this video, and a cool $40,000 USD
Breguet Classique Chronométrie 7727
The 7727 is remarkable for a number of reasons, not least because it is equipped with a 10Hz (72,000 bph) engine - twice as fast as a ‘typical’ 5Hz high-beat movement. This means it offers a 1/20th of a second accuracy. To reduce the wear and tear sustained by such a high-speed system, Breguet created a lubricant-free mechanism using silicon parts. Breguet also reworked the architecture of the balance, employing two endstones with powerful micro-magnets to keep the balance staff centred and self-adjusting.
A piece of advice on old Accutron calibers. The 214 Spaceview is very voltage sensitive. It was designed for a 1.3 volt mercury battery which is no longer made. The 1.5 volt silver based battery makes them run fast. Esslinger, and no doubt others, sell a 1.5 v battery with a resistor on it that lowers the voltage to 1.3v. I'm sure it works but not in my Spaceview which needs a good servicing. Due to a change in the way the caliber 218 handles shock, mine runs well on a 1.5 volt battery. It is not as cool as the Spaceview but runs very well. Just some thoughts on the subject.
+Robert Williams oh wow thanks for the info, I appreciate it!
I would like to get an Accutron in the future, not necessarily a Spaceview, although I find it to be the coolest looking 😛 as that technology is incredible and it's a shame Bulova doesn't make a historic line with them
With modern materials and mechanisms, 18,000vph watches can be almost as accurate as 28,800vph or 36,000vph watches. Many of the world record-competing chronometers have balance frequencies lower than 4Hz.
I really like 18,000vph, especially on a dress watch, or on a 30-minute chronograph. Measuring fifths of a second seems much neater than sixths or eighths.
+ChasingTruth TakingFlak so true 😊
When you're sat there watching that second hand revolve around, just remember, thats your life ticking away.
Great video. Nicely done.
Loved the thumbnails work at the end. Very smooth. Thank you for the info.
Beats per second was confusing for me, I counted 3 "ticks" a second when it claimed 5 beats per second. The beats count starting and stopping of the hand as separate beats. Start-stop-start-stop-start per each second
great vid and info - thank you very much 👌
Kind of a Quartz geek here. Just unboxed my Bulova Precisionist 98B267 which is not so over the top lookswise. Could watch it run for hours.
GS Spring Drive
There are cheap quartz clock movements that have true, stepless sweep seconds, essentially they are stepper motors with a flywheel. It should be possible to do the same with a quartz watch. There was also a prototype Hamilton movement with the Clifford magnetic escapement, almost a tuning fork which had a smooth sweep second hand. They only built two, of which only one is known to exist.
A Hamilton watch with a Clifford escapement came up for auction in the UK only recently, which leads me to suspect that there may be more than one floating about.
Funny to watch a CZcams video that you had forgotten, only to read a comment that I had written 5 years ago.
Nice video! Thank you so much. Zoom up on moving hands in each beats are really interesting and important info for me.
Hello guys, This video has a major mistake, using beat rates for second hand movement and for mechanical balance wheel or quartz crystal beat rate at the same time and mix it regularly discussing one watch and an other. What is sure, that for mechanical watches the balance wheel beat rate has a direct relation to the second hand beat rate. But that is not true for quartz watches, because the ordenary quartz watch has a 32.768 beat rates for the quatz crystal. This rate is diveded down to one per sec, which moves the second hand. The main reason of this is battery energy saving. In case of Bulova high frequency quartz technology, they have choosen the second way of improve accuracy ( the first way is thermo compensation) namely inceasing the quartz crystal frequency ( beat rate) eight times compere to regular quartz watch. By this they give the signal rate forward to the second hand, that the reason, that the second hand of this wacht moves eight times per second, what is equal with the traditional 28.800 beat rates of a mechanical balance wheel watch. So, the movement of this Bulova's second hand is as smooth as a mechanical watch.
The beat rates of the driving part of the watch ( balance wheel or quartz crystal) is relates to the accuracy of the watch, but the final accuracy depend on many other factors too.
Anyhow, the eight times high frequency of the Bulova's precisionist watches still not the highest frequency of the industry, many many decades ago Omega produced the so called Marine Chronometer watch with 2,4Mz frequency what is about 75 times higher beat rate for the quartz crystal as the normal one.
Enjoy your watch, and all the best to you. Miklós
+mikls168 thanks for such an informative comment, I was using the Bulova 8 beats per second seconds move to illustrate how a mechanical watch with 28.800 bph moves since I didn't have a mechanical watch. The accuracy increase I mention was related to mechanical ones
But I'm not too concerned about the accuracy of my watches. I wear them for style and the convenience of being to look down at my wrist to see the time. I like a smooth second hand, others might like the opposite. In today's day and age it's easy to sync a clock to an accurate time source, so absolute accuracy is not as important as it once was. Definitely enjoyed the video.
That Bulova Accutron II movement is so smooth...love it.
+Charliegone yup it's really a thing of beauty
What a great video. I am in love with mechanical watches in general, but also have an affection for Bulova, dunno why. So I kinda want a CURV.
+Jim Rodriguez Bulova is very cool so no reason to question the affection 👍
Nice video and presentation! Thank you for doing this. The only movement speed that I think you missed is the Omega co-axial at 7 beats per second/25,200 bph, but I cannot see a difference with the naked eye between it and my 8 bps/ 28,800 bph movement pieces. I am sure there's a difference when it is slowed down.
+john doe thanks for the kind words.
if I had one at hand ought have recorded it, but it would have been hard to put it in balance on screen with the others
The Frederique Constant Slimline Monolithic is mechanical silicon oscillator that's super high beat just like the Zenith defy lab/Zenith inventor, but its actually affordable.
Those beat rate numbers remind me of the old modems bit rates in the beginning of the home internet access.
That is some nice editing there. Loved the part where you presented the different speeds one after another and the second hand continued to count from the last position of the previous watch!
Thanks 😀
Seiko Is the King of all !!! with no disrespect to swiss brands...
Hello, the Miyota 6S21 chronograph movement has a central chronograph second hand 4 bps
Bravo! This video is awesome! 🔥
The Bulova Lunar Pilot and the Bulova Precisionist both run on the 262.144 Khz. You have the preciosionist listed as a lower KhZ movmenet which would mean less beats.
The other option for a smooth sweeping hand is the Seiko Spring Drive. :) Thanks for mentioning it.
+badkid73 yup it's the smoothest, however utmost unfortunately out of my reach currently
Spring drive ? Think you can add another comparison with the zenith defy lab!
+ahxiao8 the Zenith is stil only a prototype so a chance of me getting one for a video is zero to none 😃
If with some incredible luck I ever get my hands on one, I would definitely want to do a slow motion macro shot of it's action 😊
And the older bulova accutron, I believe
That final shot is gorgeous.
Wonderful video. I'm showing my age because all the beat rates made me think of modem baud rates.
it's funny how quartz oscillates 32768 times each second, yet they traditionally limit that feature to annoying 1 bps.
Because nobody actually *needs* more than one tick per second, and if they do, they buy a stopwatch.
@@Alias_Anybody are you aware of your low IQ?
i looked into it and apparently it has to do with battery life. they say the smoother the motion the greater the battery consumption
Nice comparison! In the 1970s tuning fork movements produced by Bulova were not only very accurate, but also had nice sweeping action. Also, back in the 1990s Seiko produced a quartz movement (5s21) with a sweeping seconds hand. The sweeping movement had nothing to do with accuracy, but was rather purely esthetic.
+JKT1971 thanks, and great info on a sweeping Seiko, I thought Spring Drive was their only sweep hand quartz
And I should also mention that spring drive is not quartz. It's fully mechanical movement, but instead of oselating wheel there's a 'electric break' and the breaking power is syncronized with a quartz crystal to give ultimate accurasy. So in the end of the day, spring drive is a mechanical watch, with a twist ;)
+GTpcGaming well the power generation and transfer is all mechanical, but the regulation is done with a quartz crystal making it essentially a quartz movement, but one hell of a quartz movement 😛
Oops, if I count the number of "ticks" in a minute of the Bulova 262Khz seconds hand, while in "slow motion", it moves 6 times in a second, please count to see i I'm wrong... Also, there are mechanical chronos working at 10hz like the Breguet Classique Chronométrie 7727, but more outstanding result has been achieved by Tag Heuer that, in 2011 presented the first 50Hz mechanical chrono (which is 360,000 bph). One of the best sweeping second hand, BTW can be found on Grand Seiko spring drive movements.
Very cool, thanks taking the time to make this.
+Thomas Hardison thank you and thanks for watching :)
Beautiful video, It's very cool to see something like this, thanks.
Thanks for watching
Amazing. Thanks for doing this!
Many years ago I exchanged a gold U.S. dollar coin for a Bulova Accutron watch, but I had to get rid of it as it kept me and the dog awake at night!
Excellent video, a nice comparison. It still would have been nice to see a spring drive.
An excellent and Informative piece.
There is one between 36000 and 57600...the Seiko 8L88/ND58 and the Citizen Cosmotron have a beat rate of 43200 bph. Both are mechanical, with the Cosmotron being a hybrid movement using a transistorized circuit to provide an impulse to the balance wheel.
Thanks for the info, never knew those existed 😊👍
The Citizen is also known as the IC-12 (for 12 beats per sec).
@@wirdy1 I should had mentioned the calibre number, which I wasn't sure of at the time, which was 5800.
Comparing a Bulova Accutron or any other tuning fork watch could have been interesting too, although they also have a perfectly smooth second hand that you won't see any individual steps with.
I think Bulova Accutron and Bulova Precisionist have similar movements with smoothly sweeping seconds hand. The latter was covered in the video.
@@tophorable The Accutron tuning fork movements don't have perceivable steps under motion cameras, they are still very smooth. I tried it one time just to see, I might upload the video if I can find it, I believe I saved it.
@@brunoshow124 To be precise, I have Bulova Accutron II. It seem very close to the Precisionist series. However, I don't own the latter one or any watch from the first Accutron series.
@@tophorable Yea the Accutron 2 uses the precisionist movement. The original Accutrons had the tuning fork movements.
Fantastic video!! Thank you for sharing!
The original Bulova Accutron, not quartz but tuning fork, oscillates at a rate of 360Hz, equivalent to a mechanical rate of 1.296.000 bph.
The Accutron 2210 oscillates at 440hz, 1,584,000 bph. I had one, when rested on a table it was quite an annoying sound & it got sold on.
My Omega Planet Ocean with the 8500 Coaxial movement beats at 25,200bph.
Looks very similar to 28,800bph and apparently extends the service intervals.
Great video, thank you!
wow i'm absolutely not into watches, but recently i got interest into them and im thinking about buying one, and that's how i got here. I learn really really interesting things in this video thanks that's really cool, but i want to know, what's the price range for the higher bph watches ?
and do there is completely smooth watches ?
Speaking of which, what's that piano melody name at the end of the video? It's beautiful.
Thanks, good information, right to the point
Super interesting and informative video! Thank you very much! You presented the information very well!
Great presentation!
57k is insane! It’s butter smooth 😍
Those sword hands look very nice on the snk.
I must be the only one that likes one beat per second. Makes it easier to count seconds. I like watches that are practical. It's the only thing I find off-putting about mechanical watches.
The Seiko spring drive is really good
The first watch, Casio Edifice is a classic quartz, which means it beats at 32,768Hz or 32,768 cycles/second. One cycle is 2 beats. The second hand motion has nothing to do with the time keeping ability. Every quartz watch has a one second sweep. Unless they they purposely give the second hand a smooth sweep.
The Bulova at 262kHz means 262,000 cycles/second, so he's wrong again.
So, a watch that is 21,600bph is 3Hz. 28,800bph is 4Hz. Just take the BPH and divide by 7,200 to get the frequency measured in Hz. 28,800bph divided by 60 minutes/hour divided by 60 seconds/minute divided by 2 beats/second.
Roger Smith actually swears by 18000, and builds his single wheel co-axials with that. He claims that once you get away from pallet friction the movements become highly accurate without the need for higher beat rates, and service intervals can be upped to 7+ years. I don't think the sweep looks as nice at 5, though.
This is the video I was looking out for but couldn’t find it until now!
Thanks very much! Much appreciated!
Glad you liked it 😊
great video dude thank you
Thanks man 😊👍
Excellent video. Thanks.
I'm glad you liked it 😊
I'll be making a giveaway of a GShock watch when I reach 10.000 subs, which should be in about 2-3 weeks so make sure to subscribe and follow the videos to see how to participate 👍
Fantastic. Was looking for precisely something like this.
Tyler Brown I'm glad you liked it :)
Theyre all pretty cool! I got the seiko 5!
I have a Sieko 5 and like it but I miss hand winding . All my other automatics have that .
Fascinating video! Thanks!
The spring drive has an electromagnetic brake, which smooths out the second hand, but its mechanical component must still have a cycle which can be counted in bph.
Nope, you got it wrong, it has the brake as you say it, but it has no bph as it has no beats, it just spins in one direction with the brake making sure it spins at a constant speed
I see you are right. Thank you!
All good watches. I collect movements over dials. I have the highs and lows in this video but am missing the the movement in the Doxa. By the way "doxa" means prayer in Greek.
PS Where would the Accutron 2020 fall in this group?
So basically Seiko makes it all
From 7s26 to spring drive and quartz
Yes and then some 😁. They are a true horological giant
I have a precisionist, the sweeping hand is cool but the one I own is kinda boring so I don't wear it too much
Nice video mate, I subscribed 👍
Super summary!
I would love to see the spring drive in slo-mo.
+Fin Jan thanks and so would I... maybe one day 😊
It's a shame that the hand on the running seconds dial of the Bulova Lunar Pilot ticks twice a second, unlike the chronograph hand which ticks 8 times a second. I usually leave the chronograph running when I wear my 50th Anniversary Lunar Pilot.
