Orig. Ed Heuer Biel, an extremely rare and sought-after export example of a German Navy torpedo running time clock with the typical top-mounted indirect second and onion crown, as was customary for navy board clocks in the late 1930s, see Knirim p. 256ff
The Swiss military and precision watch manufacturer Ed Heuer was and is known for its extremely high-quality chronographs and stopwatches
The rare piece is particularly rare and authentic due to the dial specially developed for submarine use with a tachymeter scale precisely matched to the torpedoes, starting at 300 (for 3000 meters) - the maximum distance of a submarine from the attacking ship - then running down to 0 meters, i.e. the torpedo impact in the target. If no impact was heard on the torpedo running time stopwatch after this period, the commander knew that he had missed and had to reload
Above are a few example photos of these very special torpedo running time watches from Konrad Knirim's "Bible of Military Watches". It is clear that these also came from Junghans and Hanhart on the German side (the photos show a Hanhart with an identical dial/scale structure according to the specifications of the Kriegsmarine)
A super rare piece of military and naval watch history, which very rarely comes onto the market
