About this watch
The Longines HydroConquest L3.651.4.16.6 is a robust and stylish diver's watch that combines performance with elegance.

With a lug width of 21mm, the Hydroconquest comes with a well-crafted stainless steel bracelet that feels solid yet comfortable on the wrist. The chronograph feature is a highlight, providing additional functionality for timing events. The date function ensures you're always on top of your schedule. Whether diving or just out for a casual lunch, this watch feels right at home. Its impressive 300m water resistance makes it a reliable companion for underwater adventures. With a reliable and accurate automatic movement, the Hydroconquest keeps time with impressive accuracy. A power reserve of 42 hours ensures you can take it off for a day or two without worrying about winding it again. The Longines HydroConquest is more than just a watch; it's a statement piece that combines performance with elegance.
