Ultra-Chron 43mm Stainless Steel

The Longines Ultra-Chron, reference L28364526, is a 43 mm stainless steel diver with a black dial, applied indexes, silvered polished hands and Swiss Super-LumiNova. A unidirectional rotating bezel sits above the dial, and the screw-down case back sits in a case 13.60 mm thick.

The self-winding mechanical movement beats at 36,000 vibrations per hour, a high rate, with a monocrystalline silicon balance spring and approximately 52 hours of power reserve. A sapphire crystal covers the dial, and water resistance is 300 meters. The stainless steel bracelet is 22 mm wide, 7.5 inches long, and closes with a triple safety folding clasp with push-piece opening. It is for wearers wanting a robust, high-beat diver with a fine finish.
