Vintage brass pocket watch with initials J.R.

I lost my vintage brass pocket watch yesterday around 3pm. It's a small brass Westclox pocket watch with a black enamel dial, about the size of a coin, and it ticks softly when it runs. The back is engraved with the initials 'J.R.' and there’s a tiny scratch near the 7 o'clock position. It came with a worn brown leather fob chain and a green velvet lining on the inside of the case. I last saw it outside the Vintage Vault cafe on Olive Ave in the Tower District, Fresno, near Fulton Street; this Collectors Items piece has sentimental value—it's Grandpa's gift—and I'm really hoping to get it back.
