U-Boat Darkmoon 44mm Black PVD
Oil-immersed quartz watch with a 44mm black PVD steel case and black dial. Domed sapphire crystal, 50m water resistance.
Description
This Darkmoon variant is finished with a black PVD-treated stainless steel case, giving the watch a stealthier, all-black look while retaining U-Boat’s signature oil-immersion concept: the dial cavity is completely filled with a special fluid, creating a glass-free, three-dimensional black display with a visible compensation bubble for temperature changes. Black painted metal hands and beige-treated indices contrast against the dial, all lit with Super-LumiNova. The 46mm case carries U-Boat’s distinctive left-side crown beneath a curved sapphire crystal, and is completed with a black rubber strap. Powered by a precise Swiss Ronda 762 quartz movement, the watch is rated to 50 metres of water resistance.
