Bulova 1947 Douglas

This is a rectangular shaped Bulova watch. The case is 10K gold filled. The back serial number is 7266201. The face is two toned red and white with gold numbers and hands. I have not opened the case (I'm afraid I'll damage it). The watch works - winds up and appears to keep time well. It has a leather band that I think is newer than the watch, a replacement probably. I don't know the year the watch was made or anything else. I made a guess at the year above so I could submit the form. I'd like to find out the year and model name. Thanks!
