I also tried to contact the guy but no luck.
I guess one of our Munich based collectors went into the shop and sealed the deal!

The things that worried me were:
- description mentioned a cal 12 movement, but could easily have been replaced at service; common enough occurrence
- would have been nice to see a serial number...
- the gold main chrono hand put me off, but when I look at the pics posted by Mark; that was my ignorance
- the weird spacing of the chronomatic letters vs Paul Gavin's 1153, but then I did notice it is the same as the spacing on Jeffs 1163 chronomatic black dial.

Let's hope someone in the community bought it and posts pics.
