About this watch
The Longines HydroConquest L3.782.4.56.9 is a stunning timepiece that combines functionality, elegance, and durability, making it an ideal companion for both underwater adventures and everyday wear. With its sporty yet elegant look, this watch is not just a diving watch; it's a statement piece. The 43mm stainless steel case features a sleek design that's both functional and stylish, while the matte black ceramic bezel with a rotating 0-60 dive scale adds a touch of sophistication. The black dial is adorned with mixed indexes and proprietary hands, giving it a unique flair that sets it apart from other dive watches. The sapphire crystal glass ensures scratch resistance and clarity, and the closed case back enhances the watch's water resistance to 300 meters. At its core lies the Longines caliber L888.2, an automatic movement that showcases Longines’ commitment to precision, with a frequency of 25,200 vibrations per hour and a 65-hour power reserve. The watch comes with a rubber strap that provides exceptional comfort and a lug width of 21mm for easy customization. Weighing in at 11.90mm in height, the HydroConquest sits comfortably on the wrist without feeling bulky. With its round shape and water resistance of 300 meters, this watch is a serious contender in the diving watch category.
