In the past, Hanhart supplied the Navy with chronographs, including the single-button "Calibre 40", and stopwatches. Today naval officers, leisure sailors and divers wear wristwatches or use stopwatches from Hanhart both on and under the water. The striking fluted bezel with inlaid red marking of the Primus Diver is reminiscent of the design of the watch manufacturer's legendary chronographs and is realised as a concave, unidirectional rotating bezel featuring a scale for calculating the dive time. It can be adjusted to an anticlockwise direction and has a detent set in steps of a minute.
