@@remionthemoon It just unscrews via the large central screw as with all previous Seiko.

@@spidiq8 I thought there was more to it, due to the bearings around the screw. Thanks

@@ALPINA527 Glad it helped. Bloody horrible isn't feeling stranded like that, exact same thing that happened to me. They absolutely should be ashamed especially for what we pay in road tax and taxes in general.

@@trucktruck588 Thanks, glad you enjoyed it. You should wear yours. They're lovely watches.

@@juanlgsanchez Glad it's helpful. Some of the parts dial side can be fiddly on these.

@@spidiq8 Yes, I think I´ll be unable to fix it. It is very difficult

@@juanlgsanchez Patience and practice are the key components of any watchmaking so if you persevere and just take a break if you feel you're getting stressed you should manage it.

@@spidiq8 Thank you. I have finally achieved it!, thanks to your video, which has been a perfect guide to achieve it.

@@basedchad534 What?

Glad it helped you out.

I love this one but honestly there's very few Jaeger LeCoultre designs I don't like.

Umm, ok?

Maybe the incorrect name for that kind of hobby tool but good for 0 rincles too!

Thank you and yes I found the same. It feels much easier C more controllable using a finger of either hand. I hope you enjoy using it. Once you've gotten used to the zone focusing guesstimation these are amazing cameras. Thank you for the subscription and I hope you enjoy some of my other videos.

@@spidiq8 You would be doing the Rollei owners a huge favour by creating a video with the tight shutter speed dial problem in the title for searchers and demonstrating this method of overcoming it. Might save some inappropriate use of the dreaded Wd 40 ! I’ve recently bought a 35S which is great so was checking the 35B out before considering listing it for sale. Discovered that the B setting is not holding the shutter open on pressing the button so was looking round for a cure. If I can’t find one I’ll have a good reason for hanging on to it! Thanks again.

Certainly, you're missing that we calculate amplitude from drop and lock of the pallets on each rotation. While the balance wheel rotates a full 360 degrees that's halved because the pallets actuate with each directional rotation and the point where the impulse jewel interacts with the pallet fork is about halfway in that full rotation clockwise or anticlockwise. Hopefully that clarifies things. It's trickier to put into words than show visually.

I remember the early ones having the springs and levers. I think I mention it in the build somewhere. The overall design of those rockets was incorrect to the movie though.

I believe you could yes but the important thing to remember is don't flood any solvent in there that can creep into areas it shouldn't be. Now I'm no camera expert and any decent tech would tell you the 'proper' way to do it would be a full strip and service of at least the shutter assembly but as a quick bodge you can try like this. My thinking was it was worth a chance given it wasn't too expensive.

That's an excellent question and I honestly don't recall I'm sorry to tell you. It was so long since I did this and I've only ever had a couple in. Are there any tech/parts sheets on the group? Edited to say unless it has a built in spring like some Seiko parts then it must have one. I'll rewatch my video to see if it sparks any memories.

Okay, quick check of the rebuild video shows it about around 11 minutes. It's a fairly standard shepherd's crook style. czcams.com/video/PMopyo47qiE/video.htmlsi=mX2Q1cVsGcxp3Fnf

@@spidiq8 Above and beyond--Thank you!

@@1rightrev You're welcome and glad I could help you.

Thank you. I have an updated version of this video with better audio here. czcams.com/video/tcSBK0l5Lbw/video.html

To buy or to have serviced?

@@spidiq8 to buy, but also how much is servicing for this watch? Thanks a lot

@@BokiPetrovic88 I believe new they were around £1200 and I'm not sure if this specific model is still available but there'll be something similar. Pre owned I would anticipate anywhere between £600 at the low end to perhaps £900 at the higher end. But you must take into account age as well as condition and if it's been serviced. If it's 8-10 years old and hasn't been serviced it will be due one to ensure there's not excess wear internally. A service will range between £300+ depending on the watchmaker.

@@spidiq8 ok great, thanks. I hope some new watchmaking videos coming, really enjoying your videos with explanation easy to understand. Thanks

@@BokiPetrovic88 Thank you. I hope to get some filmed soon when I start on my own projects as I've been so busy with others I've not had the time to film and edit much of anything.

There is no grittiness and it winds smoothly. I'm currently wearing this exact watch just now and it gets a lot of regular wear.

Glad I could help. They're horrific aren't they, whoever designed that really hated people in general I think. 🤣

What brands names are the watches that the PT5000 have failed on, just out of curiosity?

@@nickjohnson217 Proxima and Cronos

The environment where the watches are cased and the storage of the movements beforehand are the main contributors to early failure or poor running. Even a cheap nasty DG2813 cleaned and lubricated will run reasonably well for a long time. Most of these factories are buying movements in bulk with the most basic assembly and lubrication and the same applies to NH35's, they simply have more 'leeway' in their assembly than the ETA2824-2 this is based on and that's why they're less accurate but they can fail just as easily. Frankly when you pay between £80 and £150 for a watch you cannot expect careful assembly in a sterile environment. It's the equivalent of 'I have a mate that can do it cheaper'.

I'm not taking on any more work currently, i'm in the process of clearing my workload of customer watches and trying to get to some of my own projects and filming for youtube but thanks for the enquiry

That's interesting, thanks. Unfortunately i'm not a camera repair person, just beginning to tinker internally with them though many mechanical time parts are similar to watch movements i'm finding, just larger and less susceptible to dirt stopping play. You might be able to find a service guide for the camera but if in any doubt i'd look for a camera tech who is familiar with this model of camera. I'd like to get this one working again but it's not high on the list due to the lens not being he best and numerous other waiting projects.

I've intended to re do this video for some time and if I ever dig out the packet I will. At least the explanation of what i'm doing is there.

The anser to this is always, 'maybe'. Is there a direct replacement drop in? No, the only exception to this rule so far is the Seiko NHXX series which will replace the 7S26 movement.

The crown tubes are always a replaceable part if they're a screw down crown, depending on the case it will either be screwed in place or press fit, either way you need a suitable tool and very likely heat, to remove and thread lock to replace with a new one if you can find a replacement part, this in the main problem with chinese cases etc. often it's cheaper to buy a whole new case from aliexpress or similar.

@@spidiq8 Thank you so much for this insightful response! I've had contact with various brands about replacing crown tubes and a lot of them told me it wasn't possible to replace them as they were an actual part of the case. They don't want you to take their watches to your local watchmaker I guess.. Thanks again for your reply, really appreciate it!

Format in camera. It'll give the option to format without deleting ML or to hit the trash button to format and delete ML. Just use the first option and don't hit the trash button, card will format as normal and the camera will restart.

At least it's not the 'worst' eh.......

@@spidiq8 Thank you

I also did 2 years .mechanical/electrical engineering and really love this subject and want to get into it more.

For a first one to build confidence I recommend a brand new Seagull ST36 or the ETA6497/8 it's a copy of. Starting with a brand new one will tell you if you've rebuilt and lubricated it well as it will already run so you're not trying to diagnose faults from scratch. These movements were pocket watch movements before wristwatch and are a stalwart of the watch industry, they're as simple as they get and the size is great for handling a practice, most students begin on this. Things like the Seiko 7S26 / NH35 etc are ok but they have some specific Seiko foibles so i'd suggest those if you primarily intend to work on Seiko for mods etc. After you've mastered the ST you can move to one of the ETA auto copies such as the PT5000, the beauty of the chinese clones is that they're legal exact copies, (due to patent expiry) and they affordable.

Brilliant! Thank you!

did the lube in main spring barrel fix the gritty winding?

My particular one, (because i'm picky possibly) I would say was inadequate in the lubrication accuracy and amount, some slightly messy application. I don't know if that's common but as is i'd have expected to see timing variations after about a year but I would expect it to still be running. Because these are produced more cheaply than the Swiss counterparts there'll be corners cut re the cleanliness of assembly lines and whether the lubrication is automated or manual. A well calibrated auto oiling line will have more accuracy than manual. Think monday morning enthusiasm to friday afternoon quality in a factory environment. I've disassembled cheap DG movements before for fun and found them bone dry from brand new, they're the type you used to find in old fake watches and they'd run for maybe a couple of months.

Yes it did, the grating was from the bridle slipping with inadequate application of braking grease.

Nice one spidiq8 :)

Thanks for the enquiry, i'm not taking on any watch service or repair work currently as i'm trying to clear my current workload.
