What makes this timepiece exceptional
With its cushion-shaped case and fluid lines, this chronograph has been designed for divers and timekeepers. Its oversized case allows you to easily read the graduated bezel as well as the large tenths of a second and minute counter. Covered with solid mineral glass, the case can withstand a pressure of 20 bars, allowing the diver to descend to a depth of 200 meters. This chronograph bracelet patented by Longines is also equipped with a second hand with a graduated "Vernier" scale at its tip, for quick and precise reading to the nearest tenth of a second. The chronograph movement manufactured by Longines also includes a flyback mechanism.
