Since I had to change the battery, I thought I would snap some photos of the inside for anyone who may be interested.

The watch had stopped on 31 June.

The case back is held by 6 slotted machine screws. I used a Craftsman jewelers screwdriver to loosen them.

And this is what it looks like inside.

The battery has a cover that keeps it in place. It is held by a single machine screw, that has already been removed in this photo.

All back together. But the second hand did not zero. So I had to zero it manually. This watch has 16 segments per second. I had to push the button several hundred times to zero the hand.

The original battery lasted about 3 years. I measured the voltage of it after I removed it and it was down to 0.14V

I really like that the case back is held on by screws. Makes it much easier to get off than other styles.
