Habring² Chrono "COS ZM" Pilot, 42mm stainless steel case with sapphire crystal on a NATO strap and an additional grey calfskin strap. Serial #02-2020.
It features their patented Crown Operated System (COS) for the operation of the chronograph... and ingenious system designed by the Habrings to start, stop and reset the chronograph by turning the crown rather than the conventional pusher system. This particular watch is designated ZM (Zentraler Minutenzähler) which records elapsed minutes on the central axis by way of the arrow hand.
***Update*** Black Dial variant now completely sold out. The white dial variant can still be ordered while supplies last.
