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.
It looks like there is a triangle in the relief cut just to the left of the B in Bulova.
Probably a ladies sport watch and really nice. I would go with 1926 based on the case serial #.
1926 Bulova Unknown for now
Beautiful condition considering the age. I agree it could be dated 1926 as Bulova Unknown
It is an unknown ladies sports watch, that came with a 6T or 6AT, a movement only used on this model. This model is found only in 1926 and 1927
Movement is based on the FHF 344, as is the 6TA and 6TAA. This is an oldie indeed.
I am going with 1926 Unknown. Can't find a match either.
