Description
NTH Swiftsure Automatic Black
The 2K1 Subs are our tribute to the world’s first diving watches fitted with helium escape valves, made for record-setting, deep-depth saturation diving in the late 1960’s and early 1970’s. Like those innovative watches, the 2K1 Subs are rated to 2001 feet (610 meters / 61 ATM) of water resistance. Each 2K1 Sub model shares the same oversized, lumed crown and pointed crown-guards case, with helium escape valve at 9 o’clock, a slightly raised, double-domed, anti-reflective sapphire crystal, and no-nonsense case back with minimal decoration. While the case of the 2K1 Subs is vintage-inspired, the Thresher is a thoroughly modern design, featuring applied markers, a beveled minute track, and a lumed, DLC/PVD hardened steel bezel. Despite its extreme pressure resistance, the 2K1’s innovative case is still only 13mm thick. The chamfered sides and downward-curved lugs give the case a streamlined, wrist-hugging shape.
