Quick TakeThis Hydroconquest isn't just telling time; it's daring you to find an adventure worthy of its specs. With a formidable 43mm steel physique and a ceramic bezel that laughs in the face of scratches, it’s built like a luxury tank for your wrist. That sunray black dial with its glowing hands and markers? Pure underwater stealth and boardroom poise. And with an automatic L888 heart beating reliably for 72 hours, plus enough water resistance to bother a submarine, it’s ready for whatever you—or the deep—can throw at it.

DescriptionThe Longines Conquest Hydroconquest, reference L3.782.3.56.7, features a robust round case constructed from stainless steel, complemented by a unidirectional rotating bezel with a ceramic insert. The case measures 43.00 mm in diameter, with a lug distance of 21 mm, a lug-to-lug dimension of 53.50 mm, and an overall thickness of 11.90 mm. Protection for the sunray black dial is provided by a scratch-resistant sapphire crystal, enhanced with several layers of anti-reflective coating on both its upper and lower surfaces. The case incorporates a screw-down case back and a screw-in crown, contributing to its water resistance rating of 30 bar. The total weight of the timepiece is 194.1 grams. Hour indication is achieved through applied Arabic numerals and indexes, while gilt hands display the time, all treated with Swiss Super-LumiNova® for enhanced visibility.

Powering this model is the Caliber L888, a self-winding mechanical movement. This automatic movement operates at a frequency of 25,200 vibrations per hour and provides a power reserve of up to 72 hours. The displayed functions include hours, minutes, seconds, and a date complication. The bracelet is fabricated from stainless steel with yellow PVD coating elements and is secured by a double safety folding clasp mechanism, ensuring a reliable fit. This timepiece is engineered for durability and precise timekeeping under demanding conditions.
