Recently serviced by our in-house watchmaker in Jul 2026. Introduced in the mid-1990s as the flagship vessel for the legendary El Primero movement, the Chronomaster collection marked a definitive return to classical watchmaking for Zenith. Executed in a substantial 40mm 18k gold case, this early production example offers a traditional aesthetic that grounds the highly technical engine inside. At its core beats the automatic Calibre 400, a direct descendant of the world’s first high-frequency chronograph operating at a rapid 36,000 vibrations per hour via a traditional column-wheel mechanism. This piece represents a pivotal era for the manufacture and is made all the more compelling for collectors by arriving as a rare full set, complete with its original box, guarantee papers, COSC certificate, booklets, and matching serial tag.
