a few years ago I got this military watch from the german Wehrmacht. It was used in the WWII time as ordonance watch.
Mimo was a brand mark of Otto Graef, who took over Girard Peregaux in 1928. Mimo was used further on as the brand for export - just for your info.
A Dienstuhr - Ordonance Watch - was given to soldiers, who needed to have a timekeeper, e.g. Seargants, Platoon Leaders, Artillery, wrench officers and many more. This watches were registered in the "Wehrpass" - the military ID or military service book. As far as i remember the price to buy out a watch like this was 80 reichsmark.
The officers of the Wehrmacht were "Selbsteinkleider", that means they had to buy there equipment themselves, they liked tailor-made uniforms and watches like Longines, Rolex, ... mostly without D H markings. Exceptions were the pilots, they got the hanhart or the tutima chronographes as well as loads of champagne, cognac, women, ... the elite.
Mimo, Swiss Made

35 mm without crown
AS 1130 - the so called "Wehrmachtswerk" - legendary and durable - my favorite movement

It started all with this watch, which is still after 70 years in regular use. The movement makes plus 30 seconds a week.
