The Master Moonphase is Longines’ dress chronograph with a full calendar and moon phase, and the L687 column-wheel chronograph movement is the star: 66 hours of power reserve and a triple calendar with pointer date. The moon phase at six is the centerpiece, framed by a clean silver dial. Sapphire crystal with AR coating. It is the one watch that does everything a dress watch can. 40 mm, 14 mm thick, 46 mm lug-to-lug. Acquired 2026-03-16.
