Celebrating a high-frequency pioneer in underwater timekeeping
Inspired by the original Longines Ultra-Chron Diver of 1968, this next-generation Ultra-Chron and its new state-of-the-art high-frequency calibre represent the first reinterpretation of what sets Longines apart – its status as a pioneer in the world of sports timing.
Designed for lovers of vintage dive watches and high technology aficionados, this Ultra-Chron is powered by the new Longines L836 calibre, which is a high-frequency (5Hz) mechanical self-winding movement with silicon balance spring. Characterized by its ultra-smooth sweep seconds hand, high-frequency watches are prized by collectors for their accuracy. Longines takes this precision one step further, and has had the Ultra-Chron certified as an “ultra chronometer” by TIMELAB, an independent testing laboratory in Geneva, whose designation goes beyond the standard COSC chronometer certification.
The watch delivered in a special presentation box containing an additional black NATO strap crafted from recycled material.
