It says M0 so I guess that this is from 1960.
Hi bveltrop72, welcome to myBulova. This is a beautiful little watch that looks to be in very nice condition.
I would say this is 1960 LaPetite. There were many variants to this model. The ad I found does not designate one.

Thank you so much Geoff! This was my great aunt Dixie's watch. My grandmother gave it to me since Aunt Dixie had no children. It needs some cleaning but still runs well.
I'd say has nailed it on the head with the ID. A Bulova La Petite it is.
ditto
A beautiful watch and an heirloom. La Petite it is.
I strongly recommend getting it serviced by a certified watchmaker if you are going to run it. A dry and/or dirty movement can and will damage itself if not properly cleaned and lubricated.
Thank you everyone!
