Quick TakeThis Hydroconquest is a robust yet refined companion, ready for whatever your day holds. Its 41mm steel and ceramic armor shrugs off the elements, while the automatic L888 heart beats reliably for three full days. From the sunray grey dial that catches the light just so, to the bright glow of Super-LumiNova® when the lights go down, it’s a watch that means business without shouting about it. It’s got the deep-dive credentials with 30 bar water resistance, but wears just as comfortably on dry land, secured by a tough grey rubber strap. A true everyday champion.

DescriptionThe Longines Hydroconquest, reference L3.781.4.76.9, features a round case constructed from stainless steel, complemented by a ceramic unidirectional rotating bezel. The case measures 41.00 mm in diameter, with a lug distance of 21 mm, a lug-to-lug span of 51.10 mm, and an overall thickness of 11.90 mm. A screw-down case back and a screw-in crown contribute to its structural integrity and water resistance rating of 30 bar. The timepiece is shielded by a scratch-resistant sapphire crystal, which incorporates several layers of anti-reflective coating on both its upper and lower surfaces. The total weight of the watch, including its grey rubber strap, is 128.7 grams. The strap is equipped with a double safety folding clasp and a push-piece opening mechanism.

Powering this instrument is the Caliber L888, a self-winding mechanical movement. This movement operates at a frequency of 25,200 vibrations per hour and provides a power reserve of up to 72 hours. The sunray grey dial displays hours, minutes, seconds, and a date function. Legibility is ensured by applied Arabic numerals and indexes, along with silvered polished hands, all treated with Swiss Super-LumiNova® for enhanced visibility in low-light conditions.
