The beating heart of this timepiece is the automatic caliber L888, a high-precision mechanical movement beating at a frequency of 25,200 vibrations per hour. Integration of the monocrystalline silicon balance-spiral ensures constant performance against magnetic fields, offering a power reserve of about 72 hours for the hours, minutes, seconds and date functions.

The 39.00 mm round case is made of stainless steel and topped with a unidirectional rotating ceramic bezel. Designed for exploration, the watch provides water resistance up to 30 bar thanks to the crown and case back both screwed down. The scratch-resistant sapphire crystal is treated with a multi-layer anti-reflective layer on both sides for superior transparency. Overall weight of 155.0 g.

The dial comes in an elegant glossy lacquered black finish, where the applied hour markers and polished silver hands stand out for clarity. Visibility in the dark is ensured by the Swiss Super-LumiNova® treatment.

The stainless steel bracelet ensures maximum comfort on the wrist with its double safety folding clasp and practical micro-adjustment system.

Accompanied by packaging and official Longines 5-year warranty.
