Hi,
I bought a Gruen quartz pocket watch. I am not able to find the exact model of that watch as there is no other information of that watch written anywhere on it.
The serial number may be written in the inside of the back cover but i don't want to open it as the watch is under warranty provided the back is not opened. I bought the watch from a garage sale.
The back side of the watch is the exact same as the front side. Here are some pictures:

I'd love to know what model is it.
Thank you, Mars
