I really need to get a proper light box as these pics do not do justice to this watch.
USA in house 30 jewel automatic 10COAC movement, cap and KIF Duofix shock jewelled at the escape and fourth wheels. KIF Flector shock setting on the balance. West German made case. I've seen this before on various watches, and we have speculated as to the why of it, some of them certainly exist because they were sold to servicemen at PX's.
At the time, there were not a lot of watch companies doing what Bulova was doing, and a 30 jewel movt is very much top drawer. It's not a chronometer, that is something Bulova seemed to show little interest in. If they had made these slightly larger, they would be red hot right now, as it is the oversize 60's watches that seem to be the most collectible.
Split stem to facilitate removal of the movt, as the case has no back. This watch is in the queue, but is unserviced at the moment. I started cleaning the edges of the dial to some effect, as they were badly corroded. The reflector ring/tension ring is also missing from the crystal.
Commander, but the advert I found has no variants listed.
