Benrus
type 2 seal team submariner

American military watch Benrus Type II Class A, issued to U.S. special forces in 1979. This Benrus dive watch was nicknamed “The SEALs’ Submariner” within the United States Armed Forces. The Type II Class A model was produced in fewer than 1,000 units and primarily distributed to the U.S. Marines and U.S. Navy (while the earlier Class A Type I model saw an estimated production of 6,000 units). It was also manufactured by Benrus between 1972 and 1980.

A small unmarked batch was produced for Delta Force and CIA Special Activities Division, in a sterile version (with no visible markings). Benrus communicated a total production of 9,000 cases (including service modules for maintenance), meaning the number of completed watches is estimated to be around two-thirds of the total case production. It's important to note that most of these watches saw intense operational use, and many were lost in action along with their wearers during combat missions.

The Benrus Type II Class A is an automatic watch, equipped with a 17-jewel movement. It features a monocoque anti-magnetic steel case in matte regulation green, treated for corrosion resistance (the watch can only be serviced by removing the rotating bezel and domed crystal). The movement is the Benrus GS1D2 “hack feature” calibre, running at 21,600 vibrations per hour. This robust mechanism was developed by Benrus based on an ETA 2620 ébauche. The watch has a power reserve of 42 hours when fully wound.

The dial displays both 12-hour and 24-hour scales, with white Tritium-filled hands on a black background. Models that have been frequently and extensively exposed to sunlight may develop a “chocolate” patina on the dial over time.

The rotating bezel is marked for 12 hours, with highlighted minutes from 0 to 4, allowing precise countdowns. The first 20-minute segment is accentuated, often used during missions for GMT synchronization or for countdown timing of explosive charges or tactical withdrawal windows. The domed crystal is made of acrylic (plexiglass), measuring 3 mm thick to withstand heavy impact. It is scratch-resistant and anti-reflective, also serving as a waterproof cover since the case back is monobloc—similar to the Omega Seamaster 600 ProPloprof. A screw-down crown completes the water resistance system.

This military diving watch is equipped with fixed spring bars and was generally issued with a NATO strap matching the watch’s military color—similar to the one provided with this collector’s piece. On the caseback, you'll find identification and issue engravings, including the serial number and issuance date. As a collectible, this extremely rare watch is highly sought-after and enjoys a level of prestige in the U.S. unmatched by most other issued military watches.
