The watch is equipped with sapphire glass, known for its excellent scratch resistance, ensuring your watch remains clear and pristine even after years of wear. At the heart of the Hydroconquest 39 is the Longines caliber L263 quartz movement, based on the reliable ETA 955.412, renowned for its precision and longevity.

The watch features hours, minutes, seconds, and a date function, making it a practical choice for daily use. With a water resistance of 300 meters, you can take this watch diving without worrying about its performance under pressure. The rotating bezel allows for precise timing, a crucial feature for underwater adventures. Whether you're checking the tide times or keeping track of appointments, this watch has you covered. Comfort is key when it comes to any watch, and the Hydroconquest does not disappoint, featuring a snug fit that feels secure without being overly tight. The stainless steel bracelet is designed for comfort and durability, ensuring it feels good on your wrist throughout the day. One of the best aspects of this watch is its versatility, adapting seamlessly from casual to formal settings.
