Found these in my drawer. The silver one is 42 years old. Christmas present from my mom. The gold Seiko was a grad school graduation present. 29 years old. Time to go on a battery hunt.
That gold Seiko is funky! I like it. Glad the batteries didn’t leak. Is that upper left register the sun position?
I do remember that soon after getting it I needed some more bracelet links. No one in the states had them. I was in Glasgow one year and a watch shop was able to get them. They told me it was a European model
