I have had my great grandfathers Elgin watch for a while now. I used to wear it on a semi regular basis, but it has been dormant for several years now. From the serial number I have found that it is a 300 grade, size 16, 15 jewel movement made in 1904. I'm not totally sure what al that means but it seems like it was a pretty common watch.
What I am having trouble dating, just to see if it is the original, is the case. It is a Keystone case with the serial number 4829152. From the marks it appears to be solid 14k gold, but detailed information on the net is scarce.
Any help is appreciated.
Once I figure out how to get clear pictures I will upload.
