It started as a eBay Frankenwatch. Unfortunately, and obviously, the 6309 in it was useless. Also, it was completely the wrong type of crystal, just ground to fit. So, it got one of my spare 7S26's. It took a custom spacer to fit, and I had to grind a larger bevel on the rotor to fit it in the caseback. Hands and dial are Yobokies.
Edit: also, it came with no gaskets, even on the crown. So, it got a whole new set.
Thanks, I picked it because he got me a WWI trench watch as a project. That watch should probably get a post of its own at some point.
