This is the 3rd watch in the lot I picked up. It is in pretty rough shape so I wasn't even going to post it but decided it would be good for the DB to have the serial number for comparison. It is missing a crown and crystal.
It has a 19K gold filled case and is GF stamped on the end that opens. Has a 10C 16 jewel movement with no serial number.
I believe this is a 155 like the one I posted earlier this week https://mybulova.com/watches/1923-155-13473
