original Art Deco manual wrist watch made by the US watch company Bulova named Anita, see original ad. 15-jewel Bulova 6AF movement. Case appears to be white rolled gold with fully functioning hinged back. Advert that I bought the watch off: https://www.sellingantiques.co.uk/1027835/art-deco-ladies-10k-white-gold-watch-by-bulova-usa-c1930/
Watch has had another service but unfortunately doesn't keep time. Chap who serviced it said he couldn't find a new balance for it. I'm in the UK. Any advice on where I could get it repaired?
Great looking watch. I do agree that this is a 1930 Bulova Anita based on this 1931 ad. As for the balance, you can try purchasing a 6AF watch off of ebay as long as it has a good balance. They are interchangeable.

Nice watch! I agree
1930 Anita she is.
1930 Bulova Anita it is. Movement looks correct.
