The Pilot 11.2432.4069/21.C900, seen from the bench

The Zenith Pilot Type 20 reference 11.2432.4069/21.C900 is the contemporary evolution of an aeronautical legend, the cockpit watch that equipped French Navy pilots since the 1950s. The 45 mm stainless steel 316L case houses the renowned El Primero 4069 automatic chronograph movement with column wheel and dual escapement, oscillating at 36,000 beats per hour with COSC certification and over 50 hours power reserve. This model features a 20 mm lug width, complete chronograph functions, date, and GMT, with a unidirectional rotating bezel for practical flight operations.
