Silver Seiko 5 watch with engraved back

Yesterday around 3pm I was outside the Joplin Public Library on Main Street, near the side entrance by the cafe, when I realized my silver Seiko 5 watch was gone from my wrist. It’s a 42mm stainless steel case with a black dial and a sturdy stainless bracelet; there’s a tiny scratch at the 3 o'clock marker and the back is engraved with my initials 'PP'. It was a gift from my grandmother, and I wore it every day—really means a lot to me. I am worried I won’t get it back, especially since it’s the only thing I had left from her. If you found it, please message me; I’d be forever grateful.
