Very nice. Welcome to mybulova! After extensive looking in the Bulova Linebooks, in 1970 Linebook 174, I found what I think may be your watch.
Dial, diamond count and band appear to be a match. It would help to know the jewel count. I will also note that next to the date code, it appears case back is stamped "2 - ". That would seem to indicate the serial number is 2-313055. If that is the case, it's likely this watch is a European model produced for the international market.

We don't do appraisals, as there are far too many variables concerning condition and market swings. It is worth at least the weight of the gold (movement removed) and value of the diamonds as scrap. As a complete watch, it's likely worth more. Your best bet is take it to a jeweler you can trust for an appraisal. Your other option is to troll ebay completed auctions for similar watches in solid gold with 24 diamonds.
Just as a point of reference, the equivalent watch sold for $650 in 1970. Dealer cost was 1/2 of that. Adjusting for inflation, that equals $2,420 dealer cost and $4,843 retail in 2022 dollars. That is retail and not true value based on components, demand, current desirability, scarcity and quality.
