Here is a scarce Zenith Chronometer with a steel case and dating to 1968, in a very good condition and in a proper working order Zenith introduced the Calibre 40 in 1947 as the manufacture’s principal precision-grade movement for the following decade and a half. It is a manually wound in-house calibre — designed and produced entirely in the Le Locle workshops — with 17 jewels, a frequency of 18,000 vibrations per hour, and a power reserve of approximately 46 hours. The Cal. 40 was never sourced from an external ébauche supplier, placing it within Zenith’s uninterrupted manufacture tradition, one of the few Swiss houses to have always produced its own movements.
The calibre was submitted to Swiss observatory timing trials throughout the 1950s and contributed to the brand’s long record of chronometry competition awards. This watch has a stainless steel case measuring 33.8mm, excluding the crown, ths case is in a very good condition and shows only light traces of use. The caseback locks firmly and bears the correct manufacturer`s markings and serial number. The plexiglass is in excellent condition. The original silvered dial has a light and uniform patina, and shows a few small localised oxidations that confirm the dial’s undisturbed originality, with small seconds at 6 and hand- applied baton indexes.
The watch is fitted with a new leather strap. The movement has been serviced in-house and is in good working order. This timepiece is delivered with our six-month guarantee and originality certificate.
