Description
The Aquadeep represents the highest water- resistant configuration of all UNDONE diving watches to date. It is equipped with 500 meters of water resistance and features a helium escape valve at 10 o’clock. This precise air ventilation design can control the gas going out while ensuring water doesn’t get in. This high precision valve is used to manually release internal pressure, preventing the excessive buildup of helium gas when surfacing after deep dives.

Love this watch!
Color: Matte Black Dial - Titanium Case - Orang...
From the case to the band this watch screams quality. The knurling on the ring and post are great and I love the simplicity. My only issue is that the band is a little short you are a bigger guy but still love it!

Cool looking watch
Color: Matte Black Dial - Titanium Case - Orang...
It’s a nice looking sport watch although the band is bit short so I had to change it to a bigger size as I have more than average wrist. The lume of the minute arm is none existent which is very strange thing. Don’t get me wrong it’s a very cool watch as as long as you don’t check the time in the dark.

I got a great deal
Color: Matte Black Dial - Titanium Case - Orang...
First of all I did not pay full price for this watch, I bought it during a big Prime Sale plus I applied some Amazon Gift Card credits to lower the price even more. In short it was an excellent deal for me, upon receiving this watch I immediately realized how well made and how much care and attention to detail was put into creating this watch. NH35 movement has been solid so far by consistently keeping good time. Yes the orange strap is on the shorter side as many have noted before but it is a quick and easy swap to something else to your own personal liking. Overall it was a great deal for me because I just cannot find another titanium automatic 500M dive watch at more than twice the price I had paid for this one.
