Help identifying wristwatch movement

[randy]

I don’t have a shot of it…but it’s from a Genievre .
Under the glance the plate is marked ” Co 234 ” and the C wraps around the “o”.
At first I thought it to be a Cortebert,..but they are marked “Cort”.
I’m not finding anything that has that marking in any of my books.

I need a balance and mainspring.

Thanks for any detective work on my behalf !

Hello Randy,

I guess you are referring to Cyma 234, in wich case the O is actually a globe inside the C.
The dimensions for the mainspring are 1.50 x 10.5 x 0.11 x 350mm (GR3985)
I don’t have any info on the balance and I guess they may be hard to find.

Randy, I have quite a few Swiss mainsprings, I think the majority of one bunch is for wrist watches. It’s pot luck but if you have a size and better yet, a size, style and photo, let me know and i’ll have a root around..

The same holds true for staffs… I think you have my email?

[randy]

Jan, Chris,
Thank you both.
Jan that makes sense,..yes it “cradles” the globe

Chris I’ll see what I can now source, and if I need additional help ( parts ), I’ll be sure to get back to you.

Best regards,

Randy

Hey everyone.
I’ve now ordered two staffs for this from separate sources.
One specifically for the CYMA 234, and another for a Cyma-Tavannes 234.
Both have larger shaft dimensions than the original, and the overall length is off as well ( longer ). Here’s a snapshot of the marking that’s on the watch.

Are we sure it’s Cyma ???

Thanks

Longer is better randy, as you already know, so you’ll be facing a little bit of reduction work… I feel ya

[randy]

I tried with the 1st one to get it to the proper dimensions..just could get it there, but I’m going to attempt it again.
I would really like to get the proper staff though..this is for a clients watch,..and it’s pretty small,…so no room for error.

Randy, I don’t think it is a Cyma 234. From your picture it seems that your movement is a pin pallet escapement. The Cyma 234 does not have a pin pallet escapement. The Cyma logo I was referring to is this one

.

Unfortunately I cannot tell you what your movement is. Could you post a picture of the whole movement (both sides)?

Jan

Randy, could you also give the size of the movement?

Thanks Jan…I’ll get photos posted tomorrow..today’s time is already packed full. Thanks for the help !

Best,

Randy

Camera’s dead today…but it’s identical to this old Ebay listing..

Sorry Randy, I don’t know what movement this could be. It definetely is not a Cyma 234. The escape wheel looks like a pin-pallet escape wheel though the dial says “ancre” and 17 rubis. I don’t know if the dial on your watch says that as well. Pin pallet movements usually do not have a lot of jewels but Oris and Timex did make pin pallets with jewels so it seems.
Sorry that I can’t help you more on this one

Thanks Jan..I’ll keep digging !

Best regards,

Randy
