ENGINEERED FOR DEPTH

Hanhart Aquasphere Diver Collection


The Hanhart Aquasphere Collection is designed specifically for free diving. A helium escape valve is located at 10, which enhances the watch's functionality for extreme diving depth. Without a helium escape valve, the internal pressure can build up during deep sea dives. The valve allows the helium to escape safely, preventing any damage to the watch.
