I love jump hour watches, and I couldn't resist this black and white Oberon. Overpaid for it a few months ago as "needs repair," I'm finally tearing into it now. It looks like the previous owner did the old "soak it in oil to make it run" trick, but it was definitely not running. Came to me fully wound. The balance seemed free, but wouldn't oscillate, so I set about disassembly. Everything, including the dial, date, minute, and second rings are completely soaked in oil. The main plate is marked BF 866, which looks like Baumgartner's mark. Now I just have to figure out how to get the barrel open. Well, there's your problem. I don't know what that black crud is, but it was definitely gumming up the works.
How's everyone doing? Great I hope. Have some time to post a watch that I've been working on. I've learned from experience that the cheaper the watch, the more difficult it is to work on. Here is something from the 70's that represents well that kooky period. The watch measure 40mm x 38mm. The power comes from a one-jewel Bettlach 8800 with a jump hour mechanism on the dial side. An example of what makes this watch a nightmare to work on? For starters, you have to press down hard--and I mean with your body weight--on the stem release button to get it to release. The movement has what I think is a dust cover(why?), which when placed incorrectly causes the balance wheel to rub and stop--but only intermittently so that you go crazy trying to figure out what's happening... Its not me, its the WATCH!! J
