I'm always looking after early Zenith movements trying to get a picture about the beginning of these success story. Therefore I bid on a watch with a cruel round polished movement and not really useable broken case
The reason was simple. I've never seen these bridge form before and it looks quite initial. I was not really surpriced that I found more tinker inside. The hole bridge with the winding wheels was substituted. On one side I breath out because the click patentet 1907 (CH 41448) and not matching with my definition of an early movement. On the other side I get more uncertain what I've here.
- No protecting surface on the brass anywhere (gold or nickel) except the probably substitued spring house
- The cocks are orginal "just" round polished marked with the "0" matching to the movementnumber
- Movementnumber 9400
- Case number 2352302-5264 800 silver Zenith marked savonnete may be gildet in former times
- The subtitued bridge match 100% with the brige of the "classic" Zenith anker movement
- The balance cock seems to be untouched and pure brass also
Here are the pics for brainstorming with the matching Zenth anker part:
You see the tinker and the "orginal" seems to have owned stacks were you now see filed round.
Here a mix Zenith anker and this movement:
hard to take a photo but it match 100%
Any toughts or ideas to become any sence in this brass movement ? If it ever was gildet/ nickel plated it must be completely removed by a electrolytic method. I don't know if it excist and beyond gold you always have a silver layer. The surpace was definetly polished later on because of the ugly brass plaques. This truely smartly person definetly don't handelt within the movement. All edges are all right and the plaques are still there. Therefore at least two differend acteurs who worked on it..
Let fly the thoughts and write down please. we'll see if we get an idea of what happen to his movement and his orgin/age
