I am unable to open the watch so I am guessing on the date and movement model. My mother passed away and this was in her jewelry box. I think she inherited it from my grandmother.
Please help identify year of this watch. Thank you.
It would be very helpful if you could take pictures of the movement and the case back to get the information we need to be able to ID the watch and date it. You may have to take it to a reputable watch repairman to have him open up the watch. If you look on the back for a tab to silp a butter knife under and pry up gently, you should be able to open the case. Then carefully lift the movement from the case and take the pictures of the back side (non dial side) then pictures of the inside of the case back.
Check the vintage ads from 1940 - 1945.
The Case style and seriel number suggests a 1941 production Date, not 1934 as listed. Also, there would have to be a rather small 10 AN inside to fit and is more likely to be a 5 or 6 linge.
Unknown until we get pics of the movement and a closer pic of the dial that shows more detail.
What a great family heirloom. ...and now in it's third generation in your family. Too cool! Bet your Mom and Grandma would be happy to know your soo interested in it. Maybe mid 40's style as Fifth notes.
Unknown till more/correct info.
I suggest moving from watch db to forum. Too little information to even determine the year.
Have searched across the 40s and 50s and cannot find a match.
Maxchar, can you please provide more information about the watches movement?
mid 1930's may have been the correct era for this Watch after all, database ad Dated 1935:

Top Left - 'RONA'
In reply to mid 1930's may have been the by FifthAvenueRes…
I do see the similarities in style w/ mid 30's watches, like the Rona above. So like you say, Fifth, it could be from the 1930's as the owner originally thought. I think that was your point? The similarities in style, not necessarily a tentative ID.
Nearly, but not quite. No little "wings" on subject case sides, and the triple lines engraved on subject case seems to be part of the band in the ad.
