About this watch

The Longines HydroConquest GMT 41 is a masterpiece that effortlessly blends elegance with practicality, making it a versatile choice for both casual outings and formal occasions. Crafted from high-quality stainless steel, this timepiece boasts exceptional durability and a premium feel. The ceramic bezel adds a touch of sophistication while enhancing scratch resistance. With a diameter of 41.00 mm and a height of 12.90 mm, this watch strikes a balance between being substantial yet comfortable on the wrist. Its striking black sunburst dial catches the light beautifully, while the rotating bezel marked from 0-60 makes it perfect for diving enthusiasts who need precise timing. At the heart of the HydroConquest GMT 41 is the Longines caliber L844.4, an automatic movement that is reliable and efficient. With a 65-hour power reserve, you can take this watch off for a weekend and it will still be ticking when you put it back on. The movement's robustness and silicon balance spring improve precision and reduce wear over time.
