NTH Thresher 610-Meter Hi-Beat Automatic Dive Watch with an AR Sapphire Crystal #WW-2K1-TKSD

The NTH Thresher 2K1 Sub model WW-2K1-TKSD is a 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 Swiftsure 2K1 Sub is rated to 2001 feet (610 meters / 61 ATM) of water resistance.

Each 2K1 Thresher Sub model shares the same oversized, luminous 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 Thresher Sub is vintage-inspired, it is a thoroughly modern design, featuring applied markers, a beveled minute track, and a 120-click lumed, DLC/PVD hardened steel bezel.

Despite its extreme pressure resistance, the 2K1’s innovative 43.75mm diameter case is still only 13mm thick. The chamfered sides and downward-curved lugs give the case a streamlined, wrist-hugging shape. The Thresher is powered by hi-beat (28,800 BPH) precision Miyota 9015 (with date) or 90S5 (with no date). This model has a date window. It has a 42-hour power reserve.
