Hi all,

 

Wife has this fake Daytona that she loves and has been running for 8 years. I decided to give it a service. Tuff customer!

 

Most probable a dummy question, but any idea of what movement it is (see photos)? Any chance I can find a tech spec of it?

 

Thanks! bdbc06fc1f842cd47340556d90291bae.jpga4540d2884d827d7dcba142d79f9653f.jpg

I'm sure that is a Russian movement. Have you looked under the balance? The other thing to help us, take the dial side plate off and take a photo of the keyless work and upload it. That is the way to id a watch movement that has no markings.

Here you go. See attached.
There are no marks on the plate under the balance or any other marks. Quality seems fairly good. There are 20+ jewels on it. c0e79d8e74347e0a42c3e3bc5377d578.jpg7504818a04b0c7d37113d51d27100b2e.jpg7785ce5a1446490f5af3f9a3ba14ec63.jpgfdb6405f7c286f8449a6e8a2fc30c9bb.jpg

I’d say it’s possible an old Seagull movement - similar to a TY 2869, but without a date dial. Cousins lists a range of Seagull movements here https://www.cousinsuk.com/PDF/products/8164_Sea-Gull 2015 pages 15-20.pdf, but there isn’t an exact match in the current catalogue.

If you look at the dial side cover in on the TY 2869, https://www.cousinsuk.com/product/chinese-movement-list?code=TY2869M you will see the spring holes are very similar. Given the sge of your movement you may find it’s no longer made.

You will note that the balance cock and shock devices are different on yours. Sadly, I don’t know of any resources for positively identifying Chinese movements, or supply of parts, except winding stems. Tech specs are pretty limited although if you can work out the movement number you might find an installation drawin* on the net.  The movements are generally considered to be disposable, but plenty of people do service them, although probably not on a commercial basis.

I think I could be wrong about it being Russian. I was going by the finish of the movement after looking at this photo. If it were Russian the dial side would be the same sort of finish, this clearly is not the case. I have no experience when it comes to Chinese movements, as they were not around in the 70’s or 80’s.

@StuartBaker104 is right on the money that this is one of the Chinese 'TY' series watches. These have the smiley sun and distinct star clustering.

As well as what Stuart has advised, do a search around the TY601. If you look at http://www.watch-tools.de/movements-88/movements/automatic-watch-movement-caliber-sea-gull-ty-601.php for instance this looks like yours.

      Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy

      What are these Seitz B-Jewels?

      By Jon · Posted

      I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!

      Diagram for 6497 motion works

      By Jon · Posted

      Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.

      So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
