“The original Big Pilot - The 1940 @IWC B-Uhr ( Beobachtungsuhr / Observation Watch ). Featuring an impressive 55mm case in an anti-reflective steel finish, the B-Uhr introduced the higly legible dial and iconic glove-operable crown still featured in our Big Pilot watches today. B-watches were worn on a closed loop strap over the flight crew members and synchronized before each flight. IWC was is the only Swiss watchmaker to have produced the original B-Uhren design.” @chrisgraingerherr , Ceo, IWC
