This vintage find is for a lovely Bulova watch for a lady. It is wind-up. It ticks when wound and stays ticking, yet seems a little temperamental at keeping accurate time...a little slow. Perhaps a simple trip to the jeweler would be able to fix this easily. The watch is in beautiful vintage condition. The crystal is in good shape. I have not confirmed that the two stones on the top and bottom are diamonds. I have not opened the back of the case which says "10 k rolled gold plate" on the outer part. The band is in good condition with a lovely design. The clasp is stiff but works and secures well. It has loops for a guard chain, but there is no chain. The case measures approximately 5/8".
