I thought I was a good Googler but this one has me stumped. Therefore, I have come to the experts. When my Grandfather passed last year, I was left this pocket watch. It is still in the orginal box. It was presented to my Grandfather's neighbor in 1908, and when he passed, it was given to my Grandfather. He was an Illinois football coach . Markings on the inside lid bear the serial number 30804. There is also a 0.585 stamped into the lid. 2 other identifying logos of a crown on the left and what I can only describe as a pear-shaped logo on the right. I have taken 3 pictures of the watch and uploaded them to my site. If you could give me ANY information on this pocket watch I would truly appreciate it. It's beautiful, and it also still works. I'd like to do a write up on it for my website. Thank you so much for your help.
