This original WWII German dienstuhr (service watch) was manufactured for the Wehrmacht by Glycine, a Swiss watchmaker founded in 1914 in Biel/Bienne, Switzerland. It exhibits the iconic black dial, sub-seconds, and luminescent radium painted indicators as well as hour and minute hands. Additionally, these are usually marked on their caseback with serial numbers, and depending on the format of the serial number, the branch to whom the watch was issued can be determined. This particular watch is marked on its interior caseback with the serial number of "399", however the lack of a letter prefix and suffix indicates that this example was likely a private purchase. Its original mechanical movement is the Glycine caliber F283. Although its hour and minute hands can be set, it doesn't appear to wind. This pocket watch is in good cosmetic condition, however it will require a complete servicing to function. Its case diameter (excluding crown) measures approximately 50 mm.
