YEMA’s first moonphase puts a luminous moon behind a moving shadow
The 38.5 mm Senans Grande Lune uses YEMA’s CMM.22 micro-rotor calibre and a two-lobed shutter that crosses a stationary luminous moon rather than moving a conventional moon disc.

The watch is YEMA’s first moonphase and the first model in its Senans collection. The sculpted Grade X Super-LumiNova moon sits at seven o’clock, while a mechanical shutter reveals the lunar cycle across the fixed element.
YEMA built the CMM.22 from its 3.7 mm CMM.20 architecture, adding the moonphase mechanism while keeping the movement below 4.7 mm and the case at 8.7 mm excluding the crystal. Public orders are scheduled to open on November 11.
