About this watch

The Longines HydroConquest 41 Automatic PVD / Black / Bracelet / Japan is a masterpiece of luxury watchmaking. This limited edition timepiece combines sophistication with robust functionality, making it the perfect companion for both diving enthusiasts and everyday wearers. The round case exudes elegance, while the black PVD coating adds a touch of sportiness. The 41mm diameter strikes the perfect balance between presence and wearability, ensuring that this watch will turn heads in any setting. The dial is a rich black that enhances visibility, with stick and dot indexes providing clarity whether you’re under the sea or on land. The proprietary hands glide smoothly across the dial, making it easy to tell the time at a glance. One of the highlights of any diving watch is its bezel, and the HydroConquest doesn’t disappoint. The 0-60 rotating bezel is perfect for timing dives, allowing you to track your underwater adventures with ease. The tactile feel of the bezel adds to the overall experience, making it a joy to use. At the heart of this watch lies the Longines caliber L888.2, an automatic movement that promises reliability and precision. Boasting a 65-hour power reserve, this timepiece will keep ticking even if you take it off for a weekend getaway. The stainless steel case combined with the PVD coating gives it extra durability, making it a reliable companion for any adventure. With a water resistance of 300 meters, you can take this beauty on your next diving expedition without a second thought. Whether you’re scaling mountains or navigating a crowded city, the sapphire crystal will protect your timepiece from unsightly scratches. The stylish bracelet complements its bold design, ensuring that this watch sits snugly on your wrist without being too tight or loose.
