Bulova 1953 Douglas
I think this may be a 1953 Douglas.
The 8BC 21jewelled movement is marked L3.
The case is 10K White gold filled and Marked Bulova with the serial number 8070840. The dial is a grey with raised silver numerals and hour markers the hand are silver.
I bought it for a snip as it wasn't working. This turned out to be a bent pallet bridge. its working fine now.
