30 DAY PERPETUAL CALENDAR

LIKE EVERY THOMAS MERCER MOVEMENT, THE CALIBRE TM3003 FEATURES THE SINE-QUA-NON SPECIFICATIONS OF A MARINE TIMEKEEPER: SPRING DETENT (ALSO KNOWN AS THE ‘CHRONOMETER ESCAPEMENT’); AND CHAIN-FUSEE DRIVE, IN A DISTINCTIVE DOUBLE VERSION AND IN COMBINATION WITH A SET OF BARRELS DELIVERING A HEFTY 30-DAY POWER RESERVE.

A mechanical feat, this mechanism belongs to the exclusive family of astronomical movements. In addition to the zodiac, the celestial coordinates are completed with a magnificent 3-D moon sphere providing the different phases, combined with a moon age display showing – within the lunation cycle of 29 days, 44 minutes and 2.8 seconds – the time elapsed since the last new moon.
