Seiko NX Dive Computer (STN009J1) DH33-4A00 Very rare watch and difficult to find

"Introduced in December of 2000, the Seiko Marinemaster NX dive computer is the commercial version of a professional watch developed by Seiko Epson for a private experimental project in the North Sea. A massive 55mm in diameter and 16.7mm thick, the titanium case is actually water resistant to 1000 meters, while the computer functions and depth gauge have been operationally limited to 99.9m by edict of Seiko's legal department.

DH33 is a digital diver's watch featuring dive computer functions. An algorithm is programmed into it to calculate multilevel diving. The log data includes date of dive, entry/exit time, dive time, maximum depth, FO2 setting (percentage of oxygen in gas mixture), and residual nitrogen/oxygen at the end of dive.
