My dad wore this watch most of my life. He died last year and my mom asked if I wanted it. She tells me the crystal broke and it's been sitting in a bag in her jewelry box for the last 10 to 15 years. She thinks he brought it back from Korea in 1960 when he got out of the army. When I got it there was no Crystal and the dial was badly corroded. From the research I've done on the web and mostly on your site, my best guess is that it's a 23j, judging by the ad of all the 23s that I looked at here but I'm not positive. I got it with a gold Speidel stretch band which looks like the band he always had on it while he wore it. My daughter wants to wear it as a pendant to remember her grandfather. His name is etched into the back with some decoration. Other than that the back seems to be like all the other 14 karat gold 23s I've seen pictures of. The face used to be white with the gold hands and numbers and Bulova 23 jewels and self winding on face. Inside the back is stamped Bulova, 14K gold, and New York. There are also some markings scratched into it. They are hard to read but it looks like R 10303 and H 2463AP. I'm going to try to pick up another donor watch, or a dial and Crystal so that my daughter can wear it. It may have gone in for a cleaning once or twice, but other than that Dad wore it every day and there was never a problem. My daughter doesn't care if it runs, and I haven't wound it but I think it will run fine. I started disassemling it before i found this site with the help of a collector friend and his tools, and just with handling and the self winder it's moved 10 minutes or so.
