About this watch

The Longines HydroConquest 43 Automatic Stainless Steel watch is a masterpiece that seamlessly blends elegance with functionality. Its stunning combination of blue and yellow gold creates a mesmerizing effect, while the sunburst finish on the blue dial catches the light beautifully from different angles. The PVD gold coating enhances the luxurious feel of the watch, making it a statement piece whether you're at the beach or in a boardroom. Powered by the Longines caliber L888.5, this self-winding movement features a silicon balance spring, ensuring reliability and precision. With a remarkable water resistance of 300 meters, the HydroConquest is equipped to handle the depths of the ocean. The rotating bezel adds an extra layer of functionality, allowing divers to keep track of their time underwater easily. This watch strikes a fantastic balance between being weighty enough to feel substantial without being too heavy. It's as if Longines found the sweet spot that allows you to feel the quality without the bulk.
