Molnia 3602 Watch Spare Parts: Comprehensive Guide for Collectors and Watchmakers
The Molnia 3602 is one of the most iconic Russian pocket watch movements, produced from 1960 to 2008. Its design stems from the Swiss Cortebert 616, featuring a solid construction and Lepine gear train. With a large diameter of 36 mm (16 lignes), a thickness of 4.6 mm, and 18 jewels, the Molnia 3602 is admired for its reliability and longevity. The calibre lacks shock protection, sports a screw balance, and uses a Breguet overcoil hairspring, all contributing to its durable timekeeping performance.
