1962 (M2) Bulova Ladies' 14k white gold with diamond accents bracelet watch in original box

I'd love to know the current market value of the watch, and also how much I would need to insure it for, if anything. The watch is in incredibly perfect condition. There's absolutely no scratches or marks of any kind on the crystal face or any of the metal on any part of the watch or band. This watch looks like it was made yesterday! (The little specks visible by the 4 and 7 are dust.) I do have a question about the band and whether or not it is original: in the picture, you can see the words "USA" & "Champion" on the back of the clasp. Any information on this would be helpful. It's in the original blue velvet hinged box, which has no rips, tears or worn-through areas. There's only some areas of velvet that have been compressed due to storage over the years. These appear white or shiny in the pictures.

Good
