Hanhart produced watches and stopwatches for the German armed forces, including the Kriegsmarine (German Navy), during World War II era. Hanhart chronographs and stopwatches were issued to naval officers and personnel, most notably for use in submarine (U-boat) operations, such as for torpedo timing and ship's artillery.
Key aspects of Hanhart's
Kriegsmarine history:
Primary Supplier: Hanhart, along with Tutima, was a major supplier of chronographs to the German military, though Hanhart watches with specific "KM" (Kriegsmarine) markings were produced in relatively small numbers compared to the Luftwaffe (Air Force).
"KM" Markings: Authentic Hanhart timepieces for the Kriegsmarine typically feature the "KM" designation on the dial or caseback, often accompanied by the German eagle insignia.
Types of Timepieces: The range included both wrist chronographs and handheld stopwatches. The stopwatches often had specific scales designed for naval applications, like measuring sea miles or water depth for anti-submarine warfare.
Rarity: Hanhart chronographs specifically marked for the Kriegsmarine are considered exceptionally rare and highly sought after by collectors today due to their limited production.
Wartime Focus: Toward the end of the war, Hanhart's watch production was curtailed to focus on manufacturing time fuzes for torpedoes, highlighting their direct contribution to the naval war effort.
