About this watch

The Longines HydroConquest 44 Automatic is a prime contender for watches that seamlessly blend style with functionality. This watch offers an impressive combination of features that cater to both aesthetics and practicality, making it a popular choice among divers and watch aficionados alike. The HydroConquest collection embodies the spirit of adventure and exploration, with a robust design and reliable functionality that stands out from other timepieces. With its large 44mm case diameter and sleek stainless steel finish, this watch commands attention without being overly flashy. The black dial is adorned with mixed indexes and proprietary hands that enhance readability, while the luminous markers ensure that you can tell the time even in low-light conditions. At the core of the HydroConquest 44 is the Longines caliber L888.2 automatic movement, boasting a 65-hour power reserve and operating at a frequency of 25,200 vibrations per hour. This watch isn't just about looks; it's built for performance, covering all the basics with features like hours, minutes, seconds, and a date function. One of the standout features is its impressive water resistance of up to 300 meters, making it suitable for professional diving and allowing you to track dive times accurately. The rotating bezel further enhances its functionality, while the stainless steel bracelet is sturdy yet comfortable, fitting snugly on the wrist without feeling overly tight.
