Another 1951 Bulova. Nice all stainless steel screw back with drilled through 18mm lugs. Movement is a 10AUC with a date code L0. Dial has a poor redial with gold markers and luminous dots. It lettered DuoWind on the dial so I assume it is. Case back shows no factory engraving, only on the inside. I don't know if the hands are original to the watch. It did not have a sweep hand when I got so I added the red sweep luminous tip hand to it. Surprisingly it keeps good time. Measures 32.80mm less crown by 39.50mm lug to lug.
I find one watch like yours previously uploaded. After much debate, that one was ID'ed as
Watertite Duo-Wind "E"
"Watertite" being the model and "Duo Wind E" being the variant.
I personally would ID yours the same dated 1951, noting replaced hands and dial refinish. Thanks for sharing it with us. Ad below is dated 1951.
