Seiko stainless steel watch with black leather strap

I lost my Seiko stainless steel watch with a black leather strap yesterday around 3pm near the Ulster Museum entrance on Botanic Avenue in Belfast. The dial is blue with white luminous markers, and the case has a small scratch near the 3 o'clock position. On the back there's a tiny engraving with the initials 'AM'. It was a gift from my grandmother and holds a lot of sentimental value. I’d really appreciate getting it back—if you found it, I’d be grateful to reunite with it.
