It would have to be my Airman.
A good all-rounder: 24h display for cave exploration or Scandinavian winters, 2. timezone on the bezel for travel. Can be used from casual up to medium-dressy situations. 20 Atm WR and gains less than 1 sec per day on the wrist. 38 mm size means it won't look like a hockey puck when oversize watches go out of fashion :twisted:
Cheers,
Gert
