This watch is at least 50 years old. I don't know the exact age but if someone can tell me I'd love to know and will post an update if I find out. The gold seems to be rose gold, with that neat pinkish hue. It runs, but I can't say for certain it will keep good time. I would expect you'd want to have a good watchmaker check it out fully. There are also 2 small diamonds on the watch case set in what looks like platinum. I can’t say for certain but it is silver and not tarnished.
I've tried to take relevant photos of the markings I can find on it. Let me know if you would like to see something specific and I’ll send you a photo. It is small as you can tell in the first photo with the scale in the image. I think that may be a model number on the back, so if you have data on Bulova watches maybe you can find out everything about this watch. I don't know anything regarding jewel count and such, and I'm not going to try to pry the back off to find that out. I'm not a watchmaker and don't want to ruin anything.
The band is the original rose gold square style which is very flexible in all directions. The double clasp works well and the safely chain is still intact. The band is 12K filled and the watch is 14K filled. My best guess for wrist size is about 6 to 6 1/4 inch. I got that by measuring both side of the band including the body of the watch. I hope that's accurate enough for you. Let me know if you'd like any other dimension.
I hope I've described this properly. Please message me for any information you'd like to know.
