14k Hamilton

I have run across this 14k solid gold hamilton model 975p ca 1910. I found this info from doing some basic internet research. It is right at 1 7/8" inches and is missing the glass covering. It doesnt appear to be working. It is 17 jewels and the serial # is 825222. My question is....

Is this thing worth any more than the gold content?
Is it rare? or not at all?

It sure is beautiful but that doesnt always mean value.
