Airport Automatic 6106-01

The bidirectional bezel that defines the Grand Flieger Airport is now ultra-hard ceramic — virtually scratch-proof and colour-stable over years of daily wear. Two variants: Classic Blue (Ref. 6106-01, Cal. 330 three-hand) and Military Green (Ref. 6406-03, Cal. 310 chronograph with day and date). Both share a 43mm steel case rated to 20 atm, anti-reflective sapphire on front and back, Super-LumiNova on hands, indices, and the 12 o'clock bezel marker, and a Cordura textile strap on a deployment clasp. The lineage runs directly back to the 1940s Tutima pilot chronograph — these are its working descendants, updated where the material science warrants it.
