Original Hanhart, an extremely rare and sought-after export example of an early World War II torpedo running time clock in its original box with a typical top-mounted indirect second hand and onion crown, as was common with the Kriegsmarine's onboard clocks of the late 1930s, see Knirim p. 258ff (see the last 3 pictures)
The German military and precision watch manufacturer hanhart was and is known for its extremely high-quality chronographs and stopwatches, especially before and during World War II
What makes this rare piece particularly rare and authentic is its dial, specially developed for submarine use, with a tachymeter scale precisely calibrated to the torpedoes, starting at 2,500 meters—the maximum distance of a submarine from the ship being attacked—then running down to 0 meters, the torpedo impact point. If no beep was heard on the torpedo travel time stopwatch after this time, the commander knew he had missed and needed to reload.
Above are a few sample photos of these very special Torpedo-running watches from Konrad Knirim's "Bible of Military Watches." It's clear that these also came from Junghans and Hanhart on the German side (the photos show a Hanhart with an identical dial/scale layout according to the Kriegsmarine's specifications).
A super rare piece of military and naval watch history, which only very rarely comes onto the market
