That band is gonna look great on that watch!
Mint Kriesler, came with and is possibly original (?) there's an ad with this model and very similar band floating around somewhere. Crystal is not original and will be replaced, it's all in the details... Tarnish on the Bezel between the raised numerals looks bad currently but it's cleaning up.
* This style was so far out of the box for Bulova in 1950 - I believe it to be a Frank Lioyd Wright design. No confirmation yet.
I tried to do some research on the F. L.W. connection but didn't find anything. Good luck with that one.
