How much is my Hamilton pocket watch worth?

I found this beautiful little pocket watch when cleaning out my grandmother's (who passed away) closet. When I open it up it says 14k gold filled. It also says Hamilton watch co. Lancaster, PA. 17 Jewels Adjusted. 912.

Anyone know anything about watches?
