This vintage Bulova watch was manufactured in 1951 (has an L1 date code on the back). It has heavy signs of wear that can be cleaned up. Biggest issue is a crack in the crystal, so it would need to be replaced. This can be seen in the first picture above the "6". Has luminous hands but they no longer glow. Has a matching gold metal expansion strap. I cannot give any information on whether any parts have been replaced. The watch still runs and has no issues telling time. Message me if you would like more pictures.

Please see link below for confirmation on this being the correct watch:
