Vintage Hamilton Watch Forums

I think you're onto something, but as with most things Gruen, it's rarely simple or straightforward. This one quite clearly is marked with a "2". This pre-supposes there must be some marked with a "1". Where would these fit in?

Regarding your pocketwatch, the crown is a German mark certifying the gold content for items imported into Germany. I believe the anchor mark is the trademark of the Seeland Watch Co. of La Chaux de Fonds, although I don't believe they were the maker of the movement. It was quite common at this time...

I do not believe the gold hands would have been correct in any case. As these w...

I think Stan is referring to Dale Sutton, who owns and runs Time Machine Repair service.
I've dealt with Dale and can recommend his work with no qualms.

Adam,

I have the parts which I can send, or you could send me the watch if that works better.

PM if I can help.

I believe that 1860-1875 is a fair estimate for the date of manufacture, and I agree with Jerry that the movement is quite obviously a fairly standard Swiss lever movement. I also believe that the entire watch, including the case, is Swiss made, as there are several details of construction that are ...

Your watch is a type known as System Roskopf, and likely dates to around 100 years ago. These were rugged and serviceable watches, popular in Europe and the Middle East.

You can find lots of information by searching Roskopf online.
