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 caseback with the serial number "D 76797 H", denoting use by the Heer. Stamped on the caseback's exterior are the markings "STAHL BODEN" and "WASSERDICHT", which translates to "STEEL BACK" and "WATERPROOF", respectively (buyers should no longer rely on the waterproof claims of vintage timepieces without first undergoing professional testing). Its caseback has seized up due to corrosion, however we have no reason to believe the original mechanical movement has been tampered with in any way. This particular manufacturer utilized the caliber A.S. (Adolf Schild) 1130 - known among collectors as the legendary "Wehrmachtswerk". This watch is in good, running condition, however it could likely benefit from a complete servicing. Its case diameter measures approximately 34 mm, while its stationary "spring bars" are 18 mm wide. The last image shows the timepiece under ultra violet blacklight.
