This 1960's Zenith Diver Reference A3637 is a very rare vintage diver's watch. With its cool design, the "Big Lemon" was definitely ahead of its times. The Zenith Diver A3637 owes its nickname to the large 43x50mm case and the "tasty" lemon color of the dial and the bakelite bezel. Technically, this watch has a lot to offer. The guaranteed water resistance of 1000m made the Zenith Diver a reliable instrument of a professional diver.

The condition of this watch can be described in one word: nonreplacable. The case is unpolished and sharp. The dial is in a NOS condition. The original company's seal and the engraved serial number are still visible on the case back. This indicates that this Big Lemon was almost never worn. Evenly aged hour markers with beautiful patina make the watch authentic and honest. The original tritium lume is intact in all parts. The heart of the watch is the automatic caliber 2542PC, which is among Zenith's most stable running movement. An original Gay Frères (GF) bracelet from 1968 in excellent condition is included in the offer.

To sum up: the NOS condition of the watch, with its all original parts and Gay Frères bracelet makes this Big Lemon almost not to be found on the vintage watch market and is undoubtedly a keeper.
