310.92.44.51.01.004Ref

The 310.92.44.51.01.004, launched in 2025, comes in a 44.25 mm polished-and-brushed black ceramic case (15.09 mm thick, 50.0 mm lug-to-lug, 21 mm lug width) with a polished black ceramic bezel featuring a Liquidmetal tachymeter scale. The polished black ceramic dial has a tricompax layout—small seconds at 9, combined 60-minute/12-hour recorder at 3, date at 6—and all hands and applied indexes are 18k white gold filled with light green Super-LumiNova, except the PVD white-gold-plated central chronograph seconds hand with a red tip. Water resistance is 50 m, AR-coated sapphire crystals are on both sides, and the self-winding calibre 9900 (column wheel, METAS, 15,000 gauss, silicon balance spring, twin barrels, 60-hour reserve) powers it; it is supplied on a black rubber strap with a lunar-surface motif on the underside and a ceramic foldover clasp with ceramised titanium frame-spring folders.
