Brand new to the Archive Series, the MIL-SHIPS-W-2181 is based on a prototype that was never commercially launched, making 2021 the first time watch enthusiasts will have the opportunity to own this luxury timepiece. The sport watch was inspired by a timepiece developed for the U.S. Navy, and it has a unique paper strip on the dial that indicates if moisture has entered the watch, and will change color should the water resistance — up to 200 meters — ever start to fail. Another unique feature of this watch is that the top ring will only rotate once it is pressed down. The black matte dial is set into a stainless steel case, and has a slate blue NATO strap made with a finely-woven nylon material made to withstand continuous contact with water. This unique watch is versatile enough to be worn every day, but has the features to stand up against any other sport-style watch on the market today.
