The Aquadeep represents the highest water resistant configuration of all UNDONE diving watches to date. It is equipped with 500 metres of water resistance and features a helium escape valve at 10 oโ€™clock. This precise air ventilation design can control the gas going out while ensuring water doesnโ€™t get in. This high precision valve is used to manually release internal pressure, preventing the excessive build up of helium gas when surfacing after deep dives.


The Aquadeep is housed in a Grade II Titanium case with a sandblasted finishing.
Titanium has the highest strength-to-weight ratio of all known metals and is 40% lighter than steel; hypoallergenic as well as being highly corrosion resistant to sea water, chlorine and much more, titanium is stable in extreme temperatures, making this the perfect material to complement any serious/sunday amphibian on their next dive adventure.

Helium Safeguard

The Helium Escape Valve is vital for deep-sea dives. As divers descend, tiny helium atoms can enter the watch. Without a release during ascent, these expanding atoms could damage the watch. The valve automatically lets out the helium, ensuring the watch's safety during deep-sea adventures.
