I went to the latest watch show in Bangkok. At BALL booth, they showed me the latest model the Trainmaster Moonlight Special / Perpetual Calendar LE 999 pieces ( black face ).
The watch is using a ETA 7751 ( see through back case ).
Sorry I couldn't take any photo but available in BALL website.
Perpetual Calendar watch is kind of classic watch so when BALL release their version, I don't know if it is the right combinason or not in term of design. The feeling is quite the same for the BIG PILOT previously. Sometimes the original look is so simple and perfect that it is very hard to up date it.
Any other member have seen it in person and could comment ?
