I picked up a 1967 M7 Bulova Accutron at a Garage Sale this weekend. I took it home and found that it had a quartz movement. It looks like it has a gold cover to it. Anyone seen this movement and know what model it is? I assume it is a replacement but I could not find this movement info. BTW...I am getting a pulse with a 392 battery but the watch does not advance. I am ordering a 384 to see if it makes a difference.
