Lost gold wristwatch with brown leather strap and small scratch on glass face at Glen Valley Park, Twin Tiers NY/PA.

I lost my gold wristwatch at Glen Valley Park in Twin Tiers NY/PA on Saturday while enjoying a picnic with my family. It has a distinctive brown leather strap and a small scratch on the glass face. I realized it was missing when we packed up to leave. I would really appreciate any help in finding it as it holds sentimental value.
