I had some really old (but still in package) batteries and replaced the old batteries. Didn’t turn on. Not sure if my batteries are still good. It looked good inside. One old battery had a tiny bit of corrosion, but it didn’t affect any of the prongs. Maybe somebody else can get this moving.

Additionally, the leather strap holder popped off. It can be reglued. Or the band replaced.

Still a very old, cool watch.
