By TLex I think I'm having deja vu! I first posted the HANHART Primus Diver (here) in 2009. HANHART have since added a DLC finished model to their collection of stainless steel and 18 ct. rose gold, otherwise the Primus Diver remains unchanged. Apart from the lovely lume job, each diver features a smart red anodized aluminum Chrono pusher. I should add that the Primus Diver is diver only in name; its 44mm case is only rated to 100 meters.
From HANHART 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 realized 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.
