Vintage pocket watch with owl engraving

I lost my vintage gold-filled pocket watch yesterday around 3pm. It's a 1920s Hamilton with an owl engraving on the back and the initials 'A.R.' faintly engraved inside the lid. The watch has a small dent on the rim and the attached chain ends with a brass clasp that's a bit bent. I was browsing the downtown Scottsbluff antique row along Broadway near the old courthouse steps when I think I last had it, just after ducking into a tiny bookshop on 16th Street. This watch was a gift from my grandfather and holds a lot of sentimental value; I'm really hoping to get it back.
