According to date code on movement , 1945. There is no date code or other markings on the outside of case.
I've noticed there is another one like it with a lot of questions of it's case and markings : I have a 1949 thats almost Identical and it has year on the inside along with serial, however this has 265 and no date..






I love these watches. Sadly this one is an Unknown without an ad to support it. Like this one https://www.mybulova.com/watches/1946-unknown-5678?page=2 It could be a variant of the Practitioner but we haven't found an ad for it yet. Like the American Nurse had both versions.
Unknown for now

Well yes you are right. Like this one https://www.mybulova.com/watches/1945-watertite-10291 I am not sure what the differences are between the Unknown and the Watertite. Probably the sealing and back.
