1945 14K Rose gold plate Squadron "B" on original JB Champion Rose gold plated scissor band. Photo color is a little off, case and band are indeed rose gold and face is copper. Movement stamped with a "O" in lower right corner below the hairspring wheel. From an estate junk drawer as seen. Very minimal high point wear to plating, scratches in crystal that wil all polish out. This one is in my "to do" box. Broken mainspring, everything else appears ok.
I missed case shape above if a panel member would be so kind as to fix it?
edit: Thanks Jabs!
Squadron "B" with original band it is

I agree with Squadron 'B'. Nice original watch, I can still see some of the rectangular seconds track. Looks like the model came with different hand styles.

Good eye, I never saw the seconds track remnants until you mentioned it.
Squadron B it is.
