Bracelet watch with chain. Currently looks silver. The 3 lines of engraving on the top of the back read "10K Gold Filled" "Bulova" "L3". The number at the bottom of the back is "358150". The bands are engraved with "Bulova" "1/10, 10K, G.F." This was my mother-in-law's. I'm trying to find out more information about it. I was guessing 1950's which the date code of L3 says 1953 so that sounds correct. From the little research I did, it looks similar to the American Girl but the numbers don't quite match.
Welcome to myBulova and thank you for sharing your mother-in-laws watch with us. A very nice American Girl "J" like this one https://mybulova.com/watches/1952-american-girl-j-5743

It's hard to see the color, but I think I'm seeing white gold color. If so then this one would be a 1953 Bulova American Girl "R".
