Another of my "what the heck is that" purchases. External serial number is only 6 digits long. Based on not knowing if s/n is missing a digit (either first or last) I dated it by the movement. Outside marked "Bulova" on s/n end and "10K rolled gold plate" on other. No markings on inside of the single hinged case back besides a scattering of jeweler marks. Movement has a date code for 1934.
Case is 2 tone (yellow gold top w/white sides) and watch has a matching 2 tone band as received, with "Jimmie" engraved on clasp. Mismatched seconds hand.
When received, it would only run face down. I wound it and let it sit face down for 23 hrs and it kept time. At that point, I wound it again and flipped it over. it now runs and appears to keep time face up on the wrist.....weird. Does not appear to have seen much wrist time.
My best guess is 2 tone Commander variant. Whatever it is, it appears to be a first for the database.
