About this watch

The Longines Hydroconquest Chronograph Quartz is an exceptional timepiece that embodies the perfect blend of style, functionality, and luxury. Crafted from high-quality stainless steel, this watch boasts a robust construction that's both durable and premium in feel. The striking blue dial evokes a sense of the ocean, making it a perfect match for a dive watch. With a round shape and 41mm diameter, it sits comfortably on the wrist, striking a balance between presence and wearability. The rotating bezel allows divers to track elapsed time underwater easily, while the sapphire crystal glass adds an extra layer of protection against scratches and impacts. This thoughtful design enhances usability, making it a practical choice for daily wear. Whether you're timing laps in the pool or just keeping track of your daily schedule, this watch has got you covered with its chronograph functions integrated into the quartz movement. The comfortable and stylish stainless steel bracelet ensures that you won't have to worry about it slipping off during activities. With a water resistance of up to 300 meters, this watch is designed to go deep with you! After wearing the Hydroconquest for several weeks, I can confidently say that it keeps time beautifully. The quartz movement has proven to be accurate, and I haven’t noticed any significant deviations.
