Bulova 1931 Alvin
Pick this one up recently. I believe the hands are not original to this watch since the dial has luminous numerals. Seconds hand missing, but the pinon is there. The case is hinged, but missing the pins to tie into the case. Case is not marked GF, but I think it is. 9AT movement runs well. Is this unknown model worth restoring, at least correct hands and having the case hinged pin replaced?
