AutoSport labelled Zeniths are desirable vintage watches. Any reference to the motoring world was very important for Swiss watches. Zenith was not a brand much connected to the sport. That makes these relatively rare, named watches interesting. Added to this, the present watch is absolutely mint and has super “piepan”-shaped dial. The automatic movement is the same that was used in the Defy-models, and is of the highest quality. The watch dates from around 1969, which is the same year Zenith really excelled and introduced the El Primero automatic chronograph. Zenith is in every way a brand that matches Omega on quality, and a make who made their own movements (Omegas from the fifties and sixties are often based on Lemania calibers). The 34x39x11 mm stainless steel unpolished “C”-shaped case shows no discernable marks. The super starred crown tops the impression of a vintage watch that has seen very little use over the years. We have fully serviced the caliber 2552PC movement which beats 21600/hour and can be expected to run with near chronometer accuracy.
