Opened a friends watch last night, GW-330A, to investigate dead battery. It has a 2688 module. Several contact coil springs present. I think 4 total.
One was very short which I think drops in dead center 12 o'clock position. Somehow I lost it when trying to put it in. I thought it fell into the antenna cavity. I took the whole watch apart and could not find it.
Does any body have a pic of a 2688 module, battery side so I can see where all the springs are located?
