OF crew -
Following up on my Zenith A386 (http://alphahands.com/vintage-watch-research/zenith-a386-el-primero/) and Mido 5907 (http://alphahands.com/vintage-watch-research/mido-powerwind-ref-5907-deep-dive-timer/) projects, I want to share a serial number project I have been working on for the "Type XX" (well, the 3-register evolution). I am starting with the Mathey-Tissot, and once have completed sections on the case, dial, hands and movement, I'll be adding the same information for Breguet and Girard-Perregaux.

This serial number project includes information for every 3-register Mathey-Tissot Type XX I have seen on the web, including instagram, and is categorized by serial number plus traits of the watch, including dial type, caseback, hands, etc., with the ability to search, sort and filter the information.

If you are willing to share any Type XX (3 register) information you have (for your watch or others you have found) to help me as I keep building my project, please feel free to reach out. Not many of these around. And feedback is always welcome!

Good Luck! There are quite a few on here. Hopefully, they will be along soon.

 

Thanks Buck.
Have had some success tracking down those listed, but am hopeful others may spot duplicates or know of SN info (for both the Mathey-Tissots as well as GP and Breguets)
