H. Moser & Cie Monard Date

About this reference

The H. Moser & Cie. Monard Date reference 342.502-001 in platinum was produced during the mid-to-late 2000s and is no longer in current production. Collectors target this reference for the manual-wind Calibre HMC 342.502, which features a seven-day power reserve, a hacking seconds mechanism, and a modular escapement designed for easier servicing. The 40.8mm platinum case houses a solid gold dial with a distinct "big date" display that utilizes a flash calendar system for instantaneous changes. This model represents the brand’s early independent era following its 2005 relaunch. On the secondary market, these timepieces typically trade between $15,000 and $22,000 depending on condition and completeness. A notable production detail is the use of a functional power reserve indicator located on the movement side, visible through the sapphire caseback, maintaining a minimalist aesthetic on the dial side.
