This timepiece features a round stainless steel case measuring 42.00 mm in diameter, with a thickness of 11.30 mm and a lug-to-lug width of 51.20 mm. Designed for diving, the watch features a screw-down crown, a screw-down case back, and a unidirectional rotating bezel—details that ensure water resistance up to 30 bar. The dial is protected by a scratch-resistant sapphire crystal with a multi-layer anti-reflective coating on both sides.

The dial, in a matte sand-green shade, features applied hour markers and polished silver hands. Both elements are coated with Swiss Super-LumiNova® to ensure optimal readability even in total darkness, while the date window is positioned at 3 o’clock.

Equipped with the L157.3 caliber, a quartz movement powered by a RENATA 371 battery (SR920SW – 1.55V). It features the special E.O.L. function, an indicator that provides advance warning of the battery’s end of life.

The stainless steel bracelet has a 21-mm lug width and fastens securely thanks to a double-safety folding clasp with a push-to-open mechanism.

The total weight is approximately 162.0 g.

Accompanied by packaging and official Longines 2-year warranty.
