Looks similar to 1945 Brigadier and 1945 Douglas, but not the same dial and slight difference in the case. The watch band pin holes do not extend through the case to be visible on the outside (like the Brigadier). Movement is seventeen 17 jewels , unadjusted , swiss , with a mark MX(?). the MX (?) looks like the MX is followed by a small square with some marking inside. I cannot make out the mark inside the square.
Not sure about the date, but I think I am close.
Thanks Ken S

I'll throw another option in here. This could be a 14KT rose gold version of the 1945 Golden Eagle. Note this is a new model year for this name from what I can tell. See supporting add below for same case but with a different dial. Possibly ad shows a yellow gold version and this is the rose. Isn't this dial similar set up similar with other yellow/rose gold models. Unfortunately I found additional ads showing it as 10KT gold filled. No confirmation of 14kt gold. Just a thought.
