On the subject of Sinn - if you like the idea of a contemporary pilots watch - something that meets the requirements of a modern pilot, check out this link. They aren't cheap, but they are very, very cool.There is a pilot & military watch sub forum you may want to check out for more specifics. IWC, Stowa, and Laco were original makers of the WWII Flieger and are popular. Many brands offer offshoots of these styles. Others fancy themselves pilot watches and have little resemblance to these (Breitling comes to mind). Sinn is a great brand to check out if you like pilot watches.
