U-Boat Sommerso Damasco 9999

Damascus steel has a history that predates modern watchmaking by centuries, and the Sommerso 9999 puts it to work at 46mm. The case pattern is entirely individual to each piece, the unidirectional bezel carrying a spherical ceramic indicator above it. Inside, a three-level black dial presents beige Super-LumiNova numerals and hands alongside a blue 24-hour indicator at 4 o'clock and date at 9. The modified Sellita SW 200 runs at 28,800 vph with a 41-hour power reserve. A U-Boat watch that carries its provenance in the steel itself.
