Lost silver wristwatch with black leather band and minimalist white face near playground in South Coast Park.

I lost my silver wristwatch while I was jogging in South Coast Park yesterday afternoon. It has a black leather band and a minimalist white face with no numbers, only markers. I last remember having it when I stopped to tie my shoelaces near the playground area. If anyone finds it, I'd be greatly appreciative. It was a gift from my late grandfather, so it's very special to me.
