Found this yesterday at an antiques mall buried in the back of a case. It had a scratched and discolored crystal and I was pleasantly surprised when I replaced the crystal to find a beautiful shiny like new dial. This appears to be a 1955 Bulova 23 "H" based on the 1955-57 Linebook. The case is 10KT yellow gold plate with a stainless back and L5 date code. The 23J movement is a 10BPAC also with an L5 date code. Overall in lightly worn condition and running great without a service.
Case Serial No.
26.8MM Domed Plastic
