What is this movement?


Recommended Posts

I don't know the make of the watch, but I do know that it will test your patience when it comes to putting it back together again!

Anyway, I hope you find the answer that you seek...........good luck.

I cant find the ID in my bestfit books. What I have noticed with your photo is the Clutch Lever is missing.

Any other members on here that can help Henry. 

Clutch lever = yoke = return bar? Trying to get to grips with as much watch parts terminology as I can!

40mm puts this at a 17.75 ligne movement. This isn't as common as 18 ligne movements but I've looked at a lot of both and come up blank with a match to your movement. [Just to double check ... your first picture shows your movement with a holder ring; the second without so the 40mm should be the measurement without the ring. Yes?].

Tantalisingly there's a '408' on this movement ring but I can't find this relates to anything relevant. Are there no other marks on the movement e.g. if you remove the balance is there something there? Also did the movement come with a dial; does this offer any clues to at least a brand that might point in the right direction?

I'm not sure but there were not many using that kind of quirky setup with the Yoke on the right side and the spring on the left but it was used by MST on like their 15X (154-158 and 139) movements. Maybe some movement based on those?

    • 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
    • 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!
    • 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.
