The watch is powered by the L157.3 quartz movement, which is powered by a RENATA 371 battery. It features the special E.O.L. function, a device that provides an early warning when the battery is nearly depleted. This module precisely coordinates the hour, minute, second, and date functions.

The dial stands out for its sand-blue hue with a matte finish. It features applied hour markers and distinctive pink hands, all treated with Swiss Super-LumiNova® to ensure optimal readability even in total darkness. The date window is located at 3 o’clock.

The round case combines stainless steel with a rose PVD coating on the bezel and accents. It has a diameter of 42.00 mm, a thickness of 11.30 mm, and a lug-to-lug width of 51.20 mm. Designed for diving, it features a screw-down crown, a screw-down case back, a unidirectional rotating bezel, and sapphire crystal with anti-reflective coating on both sides. It is water-resistant to 30 bar (300 meters) and weighs 162.0 g.

The bracelet, which has a lug-to-lug width of 21 mm, is made of steel with a rose PVD coating. It ensures excellent stability on the wrist thanks to a double-security folding clasp equipped with a convenient push-button release mechanism.
