Hi All,
I have adquired this watch some time ago, but it needed a very big intervention in the SPA.
Dial is aged, a lot... but I still love it, and also case is heavily polished.
Model is 12267, case number 1232674 (between 1945 - 46 I presume), nad movement 481 with number 282911.
What excites me more about this model is the striped finish of the movement.
I have not seen many, if any UG with this finishing in the movement, but I would like to have your opinion.
Thanks in advance

 

The finishing of the movement is awesome

 

I doubt this was done at the factory.

 

I have never seen Geneva stripes on a UG. Kinda fun. Seems unlikely to be stock.

 

Why?
So, who have done it?

Is it not possible that a limited number of movement might have been finished like that?
Could UG tried to use cotes de Geneve finishing, and them based in time consuming or costs abandon the idea?
Thanks

 

There are a bunch of zenith cal 136, 146 And 156 that have the exact or very similar finishing. These are all Martel movements and are the equivalent of 281, 285 And 287 UG calibers which mean Martel did finish their movements in such a manner (I would think it would be too troublesome for Zenith to carry the extra work at their own assembly) so I won’t rule out Martel doing the same for UG. I haven’t seen a UG finished like this though.

 

The finish would have been applied before the bridges and plates were machined from the plate, so applying them after it had been assembled would seem like a fool's errand, indeed. Or is this a more recent way of doing it?

 

I believe the finishing to be indeed original to the watch (even though very uncommon indeed).
As ELV web said, Martel was indeed capable to mke such a finishing, they did it more often than not for Zenith, hence the skill was there.
I have seen it once before on a UG, but I do not have a picture saved down to back it up.
If this was a steel case then I would have probably thought the movement wasn't original to the watch but being a gold case it is most likely original and in there with this finishing since the beginning.

 

Thanks for all comments.
Nice to see that there is no absolut sure related to this, and also to other subjects regarding to UG from the past.
