Here is one that tricked me. I originally thought this was a Commander but upon turning it over it had a N0 date code and was a mono case. I was sure the Commander did not go into the 70s. Luckily I found it in the Line Books and it is a 1970 Bulova Sea King "BC" a first for the database. The movement is a 10COAC and has 30 Jewels and a split stem. The dial is silver with cocentric rings like a record and has an applied polished silver outer ring with applied beveled hour markers on top of it with lumed dots. The hands are lumed also. . It has real depth. The case is stainless steel and marked W. Germany. It came on an original bulova bracelet.
Case Serial No.
