This chronometer is one of 12 that were produced on order for the German Navy in 1940 after it was discovered that the launch of several torpedos at the same time caused unusual rate variations. In "Alte Uhren" 1/79, the maker of this chronometer Herbert Müller describes the navy’s requirements and the chosen solutions for the chronometers. He concludes that "only little is known about they fared in real life. I have never seen any of them again; I suppose the chronometers are all on the bottom of the sea together with the submarines." Luckily this is not so: in addition to this piece we know of two others, which are described and illustrated on page 282 ff. of "Militäruhren" by Konrad Knirim.
