About this watch

The Longines Hydroconquest GMT 41 is a luxury watch that embodies style, functionality, and durability. Its vibrant green dial with sunburst finish sets it apart from traditional dive watches. The stainless steel case and ceramic bezel enhance its visual appeal while adding robustness. The rotating bezel allows for precise timing underwater, making it an ideal choice for divers and adventurers. Protected by a sapphire crystal, the dial is resistant to scratches and offers excellent readability. At the heart of this timepiece is the Longines caliber L844.4, an automatic movement that guarantees reliability and accuracy. With a 65-hour power reserve and frequency of 25,200 vibrations per hour, it ensures precise timekeeping even after extended wear. The watch features a water resistance of up to 300 meters, making it suitable for diving and any water-related activities. Its stainless steel bracelet is sturdy, comfortable, and secure, while the lug width of 21 mm provides a snug fit on the wrist.
