Very very cool old style Kelbert watch. Serial listed on inside rear of case. Runs when you wind it, but it hasn’t been worn in decades. I don’t know the story of the watch other than it came from a long-deceased relative. Small watches are in, so this is a nice nice very small size. Per listing title, this is CASE ONLY. There are no markings RE: gold anywhere, so I would guess that this is possibly bronze or something like it. The detail on the movement is quite impressive for the size, given the age. Any questions please ask. The Vintage Kelbert Watch is a classic timepiece featuring a stylish old-school design. This analog wristwatch has a polished case finish and a compact 26mm case size, making it a unique accessory for men. With its retro charm and brand history, this Kelbert watch is a must-have for collectors and watch enthusiasts alike.
