About this watch

The Longines Hydroconquest Quartz 41 Black is a stunning addition to the HydroConquest family, perfectly marrying functionality with style. Its striking black dial and robust design make it suitable for various occasions, from casual beach outings to formal dinners. The watch's stainless steel case has a diameter of 41mm, striking a balance between bulkiness and daintiness. The rotating bezel is functional, allowing divers to track their time underwater easily, while the 0-60 markings add a sporty flair. The proprietary hands offer a unique touch, and the date function is conveniently located for easy schedule keeping. At the heart of the Hydroconquest is the Longines caliber L115 movement, designed for precision and reliability. With a frequency of 28,800 vibrations per hour and a power reserve of 26,280 seconds, this quartz movement ensures accuracy and eliminates the need for frequent winding. The watch's impressive water resistance of 300 meters makes it perfect for aquatic adventures, while the sapphire glass is scratch-resistant to maintain its pristine look. The stainless steel bracelet feels sturdy yet comfortable on the wrist, adapting effortlessly to various lifestyles.
