My friend was given a watch of his grandfather’s and asked me to tell him about it. I am by no means a UG expert. I was hoping you guys could help. It’s a Unisonic D. He says the back says: Universal Geneve 18 karat gold. Patented 2618432. He only sent these pics. No movement photo.
Any idea what kind of movement it has or what era it is from?
