Lost silver wristwatch with dark blue face and leather strap at BYU campus in Provo.

I accidentally left my favorite silver wristwatch on a bench while I was studying at the BYU campus in Provo. It's a simple design with a dark blue face and a leather strap. I didn't notice it was missing until I got home. If anyone finds it, I'd really appreciate getting it back as it has great sentimental value to me.
