So... a really interesting piece. Double date stamp on the movement X =1943 & O = 1944 (handstamped). Case has a 1943 date number.
This is the exact case of another unknown from 1943 I have here:
Case is the same... hands are close but one is variant and both are lumed.... movement I believe would be the same.
I have no ad supporting or refuting either dial variant.
Unknown for me.... I somewhat question the two tone dial... but I think it could be legitimate as we have another dial variant black/white in the same year with the Blackhawk.
Either way... the model is pretty rare as I think I've only seen 3 in the years I've been collecting...
