Other a3821-ic-930

Launched in 1972, the ref. A3821 (also referred to as 01.0180.415) is something of a hybrid watch, combining the legibility and luminescence of a pilot’s watch with the 300 metres water-resistance and double-gaskets of a diver’s watch. The A3821 was part of the first ZENITH Pilot models equipped with an El Primero calibre.

A sort of hybrid watch, it combines both the legibility and luminescence of a pilot’s watch with the 300 metres water-resistance and double-gaskets of a diver’s watch – something quite possibly unique in the history of watchmaking. The example in this set is part of the very first production lot from 1972.
