Hi, I recently acquired a 1976 bulova computron drivers style watch. It has one of the two threaded battery covers on the case back. I'm looking for one or a matching set so I can finish the watch and make it 100%. Unfortunately they aren't the same size as the accutron 214 threaded covers so they have to be from a computron that takes a 228 cell. No one online seems to have any so I was hoping someone here might have spares or a parts watch that they'd be willing to sell.
