Inherited watch from my grandmother. Don't know how to open the watch to look inside and I am not willing to try myself. Unsure if the year really is 1940 but I had to put something and the closest model I could find on here was the 1940 Carolyn model. But the top and bottom of the case is slightly different so it could be a different year.
Hello Miss Shannie, welcome to myBulova. What a wonderful keepsake you have from your Grandmother! I think watches are just about the most personal things we have. While rings have much associated with them we USE our watches dozens of time a day, they are so much more than jewelry.
I would agree that this girls name is Carolyn. Be sure to have her serviced regularly if you plan to wear her. She can last another lifetime if well maintained.
