This watch is from Canada.
Under the serial number it says N2. I didn't see this model in any of the watches on your web page or the adverts. I see similar watches, but the face is different, they have a date mechanism, the crown is in a different location and they do not have the 10K gold plate. The serial number comes up empty.
I got this watch from my Father-in-Laws estate. It was given to his brother in 1975 as the "Gold Watch" for 25 years service. He passed away in the mid 90's. I don't know when the watch was last serviced, but I don't think the battery would last from the 90's.
The watch is running but it runs fast.
