This is an interesting one. It could be a variant of the Military Miss like we see with the American Nurse and Clara Barton having both types of dials. Or it could be a Lido or another model altogether.
It has a 10K rolled gold plate bezel with a stainless back. The working movement is a 17 jewel 7AM and has a dual date stamp of 44/45 circle/triangle. I went with 1944 because the case has a 44 serial #.
Look forward to hearing your thoughts. I couldn't find a date for the ad attached or any additional ads. My thanks to Bob for transferring ownership of this beauty to me. It is a nice addition to my little square watch collection from this time.
