Do you know how to open the back of the watch? Be careful when doing so, the hands and numbers are lumed with lots of radium contaminated stuff (half-life 1600 years, so it's all still there and particles falling around inside, even if the watch is not 'glowing' anymore).

It's a Waltham 1940s military model.

The watch has obviously seen some moisture over the years, so fingers crossed that the movement is ok.

It works like a charm, this is the inside:

Serial number 31965065 = year of make 1944. Surprisingly clean movement definitively made by Waltham. Above the 'Waltham USA 17 jewels marking' (presently covered, you don't have to bend back anything, just take the entire thing out) you should find '6/0-B' which is the movement caliber.

I guess the crown of your watch has been replaced some time back in history. This is what it should look like:

I thought that ww2 era military issued watches has no brand label on the dial, only on the movement. Am I wrong?
