It represents a significant step in Yema's Millésime series, showcasing French manufacturing and complex complications.
- Limited to 150 pieces
- Price: EUR 14,500
The watch features a rotating celestial disc that completes one revolution every sidereal day (23 hours, 56 minutes, 4 seconds), measuring Earth's rotation relative to distant stars.
The Calibre CMM.32 movement, produced in Morteau, France, was developed with watchmaker Olivier Mory and is designed to withstand significant shocks and vibrations.
The movement is finished in blue and decorated with a celestial map, while the barrel cover features a world map.
The dial has a black sandblasted texture with a black PVD coating, framed by a circular-brushed minutes track, and features Super-LumiNova BGW9 on hands and markers.
The 42mm Grade 5 titanium case has contrasting brushed and polished finishes, sharp lugs, and a double-domed sapphire crystal.
The watch is presented on a black leather strap with matching stitching and a titanium pin buckle.
