About this watch

When it comes to watches, few names resonate like Longines. The Hydroconquest Quartz 39 Green embodies the spirit of adventure while ensuring functionality. This timepiece beautifully balances style, functionality, and durability. It stands out in the crowded field of dive watches and offers an impressive array of features that cater to both adventure seekers and everyday wearers alike. The stunning green sunburst dial is not only striking but also versatile enough to pair with various outfits. The combination of the green dial with the stainless steel case creates a beautiful contrast that is both eye-catching and elegant. At the heart of the Hydroconquest Quartz 39 Green is the Longines Caliber L263, a quartz movement based on the reliable ETA 955.412. This means you can expect not just accuracy but also a long lifespan from this timepiece. With a water resistance rating of up to 300 meters, the Hydroconquest is more than ready for aquatic adventures. The rotating bezel smoothly rotates with a reassuring click, ensuring accurate timing for your underwater adventures.
