BULOVA Ladies Vintage Diamond Wrist Watch White Gold

In perfect working condition, this Bulova diamond ladies wrist watch, in white gold, carries a lot of history within it. While trying to find the maker's date, inside the back of the watch, I found scrawlings of a lot of numbers, including dates. Extremely interesting! This Bulova watch is "Swiss" made, 17 jewels ( all of this info inside). It appears to be circa 1949. Mesh band with double closure lock, as well as a safety chain. The clasp on the band reads "10KG.F., underneath that, 10P. On the left side of those inscriptions, there is a triangle shape with the initials "JB". I hope! The clasp is also marked USA. I am not certain, but would think the diamond chips (top & bottom), equal 10 points. Lots of time spent on this one, but what FUN!! Questions? Please feel free to contact me. Thanks! God Bless
