Here is my full review of the MIYOTA 8215: czcams.com/video/iCIbLyXq0ho/video.html
I have a citizen watch with this movement. On a timegrapher it's all over the place, if i leave it in different positions it will gain or lose up to 15 seconds per day. But if I wear it constantly, which is how these movements are intended to be used, it runs at +3 seconds per WEEK.
15 seconds/day really isn't all that bad. If accuracy is your priority then no mechanical watch will fit your needs and you'll have to get a quartz instead.
@@KrolKazliar,liar pants on fire.
I lost a lot of Casio in my childhood do to poor battery replacement job and compromise the watch waterproofing , then I move automatic watch because it's give me peace of mind to not need regularly change battery but still require service in 5-10 years, but now I already go back to Solar quartz where battery replacement might needed just as automatic required service but at least solar quartz has better accuracy.
Notes on the NH35A: I have 2 of them, both in Invicta Pro Divers. One has a power reserve of 45 hours, the other, 48 hours. On the timegrapher, dial up, both at +\- 1 spd (seconds per day). Dial down, -4 spd, crown down, - 7 spd. I regulated one of them which was +10 spd. The other was close to spot on. Given Seiko's tolerances (-20 to + 40 spd, 41 hour power reserve), the NH35A overdelivers. And, although it's much too expensive to pay a watchmaker to service it, a reasonably adept amateur can service one. Aside from changing the battery, try doing that with a quartz movement!
Thank you for sharing your experiences!
great work, amazing videos. Please do reviews on movements like SW200/300 / MIYOTA 9015 too
Great information ❤👍✌️
Great comparison. Thanks!
Thanks for watching!
Thank You for this very concise Presentation! You are helping the. consumer make an Educated choice!❤
I have owned watches with both, and own a timegrapher. The NH35 hacks and has a bye directional rota which is an advantage. However, the Miyota has better positional variance. Both are decent reliable calibers but I would go for the NH35 given the choice. I believe there is now a Miyota 8315 now, which is meant to be very good. The Miyota 9000 series is far better than the Seiko's 6R35, which is there counterpart
I finally grabbed my first watch with an NH35... that's what brought me here. I watched a JOMW video where he broke down how special the aliexpress Addiesdive 1000m diver was for $80, and I leapt at the opportunity. Its very impressive how well it keeps time when I wear it.
Great video! Thanks for making it. The funny thing I’ve found is my watches with Miyota movements have achieved really good timing, usually -3 to +4 per day, while my seiko movements are usually more like -5 to + 12 per day. Miyota underpromises and over performs while seiko usually under promises and over performs to a lesser degree.
Great video! Not really a fan of the Miyota movement but I do really like the Seiko.
I've never had any problem with either of these movements. They have proven to be accurate and reliable movements.
My first build has a 8215, I'm so happy with it. It runs +15s p/d consistently straight from the factory. My next build will be a NH35 for sure 👌 Great video, thank you
Just curious, why not adjust it? I've got an 8215 in my watch, and I adjusted it to 0.2ms of beat error, and less than +1 second per day. It hovers around zero.
+15 s p/d? Even my 50-years old Omega cal. 613 runs better, below 10 s p/d.
What a good video, we want more videos like this, of Swiss, German, more Japanese movements...... thanks and greetings
Excellent
I bought the 007 about a year before being discontinued and found it not winding well on the watch winder. I suspected lack of rotor oil. Yes, oiling improved the winding substantially. But still somewhat stiffer than ideal normal. Seiko QC has fallen off a cliff.
NH35 is pretty cool, I had maybe 7 of them recently in my MODs. you can indeed get within 3 seconds daily variation if you have the patience to adjust the time over few day period. It can be impressive. But not all can be like this, some movements will be 10+ second difference regardless of how much time you spend adjusting them.
So which one do you prefer Sir ?
Both excellent workhorse movements I would say the seiko is better overall, however I have a real soft spot for the miyota as based off the tried and tested 8200 movement the slight rotor noise doesn't bother me and as for hacking I have found that from around 2018/19 the miyota hacks I think maybe older stock still out there without hacking if you go for a miyota ask if it hacks.Either way I feel both movements are excellent no bells or whistles they just get the job done very well great for everyday watches .
Miyota hacking lever sits next to the balance wheel. It's pretty easy to see. I guess it engages the balance wheel when the crown is pulled. The problem is whether you will receive a 8215 with a hacking lever or not. Since the 8315 is newer, I would suspect all production of 8315 include hacking but they seem difficult to source.
SEIKO NH35 однозначно лучше чем MIYOTA 8215. У SEIKO NH35 автоподзавод на шарикоподшипнике, двунаправленный ротор и плавный ход секундной стрелки. В то время как у MIYOTA 8215 автоподзавод на втулке (что даёт шум и более быстрый износ), однонаправленный ротор (меньше эффективность) и секундная стрелка тормозит, заикается (устаревшая схема в механизме). Всем рекомендую покупать часы на SEIKO NH35.
I have a couple of both. My Miyotas handle low charge or not being worn much better. My NH35's or 6R's go nuts after 20h or so.
I think it's time to compare chinese movement to japanese movement, they are not trash according to my knowledge. Especially DG2813, too cheap and CAN be reliable. Just make sure you didn't got bad luck. Quality control in China is getting better over time tho.
They cannot even made a good finishing of their clone movements lol
How do you ensure you don’t get “bad luck”? If a movement’s reliability and performance is unpredictable due to poor quality control then it’s a poor movement.
You dont.. it's a complete gamble unfortunately. QC at the Seagull factory just isn't up to par and there is always a risk of purchasing a dud.
What’s funny to me is that in my experience the best Chinese movements are the Dandong Rolex 3135/3235 clones lol
*i have DG2813 watch… When brand new the accuracy is +5s/day, after a simple adjust it can have -1sec/day accuracy.*
There's also a difference between 4R35 and 4R35B: the B variant is an updated version which has 23 jewels instead of the earlier 21 jewels.
Idk why people claim it's 24 jewels, but my Seiko Presage has a 4R35B with 23 jewels, according to the text on the rotor.
9015, 9019, 9039 whats the thinnest model? all three same accuracy and power reserve?
There are many other "clones"( movements that can be used in the same watch) of the ETA 2824 Such as the Sellita Sw200,the STP's the Seagulls etc!
Ive seen 8250... just a newer version in the 8200 family?
Just got my first miyota powered watch was a mod from eBay it’s good on timekeeping but noisier than my seiko powered watches so leaving it on bedside cabinet is a no no
I accidentally turned the crown the opposite way when setting the date on my Bulova Devil Diver with the Miyota 821d-21b movement and forced it thru two clicks, did I damage it at all?
Definitely
In my opinion although both movements are similar the nh has way way more option when it comes to cases, dials, hands and other watch parts. This is because nh comes in a watch that has so much die hard fans which creates market for parts, as opposed to to the Miyota which comes in invictas, so does the nh but miyota I don’t think has a cult classic watch that it was used in to create the same demand.
I am about to buy a Rolex case and trying to choose movements. Either Seiko NH35 or Miyota 8215. Do you have any clue if both will fit or is the NH35 too big? I have very god experience with NH36 in my Seiko 007 case and hope that will fit. Thank you for another great video!
Hi, if the NH35 fits your case, I would go for that movement. Unfortunately, I have no idea if that movement fits.
I know the 8215 fits in a deep sea sea dweller and a GMT master 2. I know this because I have them. 😃
Seiko has the licenced Magic Lever
Not oiled? Manufacturer is expected to take it apart and oil before use?
You're right, probably fairly unusual, but sometimes movements are ordered with the intent of either adding custom complications or significant amounts of decoration and then adjusted, in which case a "finished" movement is a waste and would require extra cleaning before being worked on, so the movement is more just a roughly assembled set of parts.
citizen must be upgrade their movements but its good reliable movement anyway, everyone loves tsuyosa's afterall
I have a NH35 movement.
But the next is a miyota to compare.
An Orient Movement would have been right at home here
One of these is built in Japan and one is assembled by 9 year olds in china.
Only big difference is winding direction
4:40 - Sapphires dyed red. Not ruby. That's why they're labels jewels, not rubies anymore. Rubies and sapphires are chemically the same as far as a watch cares. 9 out of 10 in hardness. Diamond is 10. Sapphires and rubies are both part of the chromium family of structure. i.e.- they're all sapphires. The ruby had more chromium which makes it red. Any other color would just be called a sapphire.
Sea-gull st 16 weeeeee
It's called seiko. Not psycho
There are counterfeit nh35 movements.
And there are many Counterfeit 8215's!
There are also many "clones" of the ETA 2824( movements with same basic length and width that can be used in the same watch) such as the Sellita Sw200 the STP,s, the Seagulls etc!
Comparing the 8205 would have been fairer.
... isn't that just the name for the identical citizen in house movement ?
There are definitely fakes of the Miyota 8200 series movemts out there on eBay and such. You can spot them by the shock protection. Probably because the fakers weren't able to produce the citizen parashock system they did put in something else. Definitely not from the same production line. Plain and simple fakes. Be careful when buying.
Rotor sound on miyota is VERY loud and annoying. I'll never buy it again!
Both movement are crap
I love miyota
The biggest problem is the 8000 series is noisy.
