Ultra Rare Gruen Precision Electric Water Proof Watch.

The watch doesn’t work! Maybe needs a new battery or service. It is in great esthetic shape, the band is not original but it is “Dufonte” swiss made. It is very solid material and I think is rare too also it fits perfect and is for the size 7.5 inch maybe to 8 inch.

If you have any question please let me know.

Thank you
