Welp. I think its a 1926 something or other.
The case is 14K gold filled. Patent date Jun 10, 1924. The movement is a 15J, 6T. There are no watches with 6T movements in the database. I couldn't definitively identify the date code. I thought I might have spotted a triangle in the lower right corner of the photo but its basically scratches.
The watch looks like the right style for the time but I think the lugs are pretty unusual for a women's watch of the time.
