Lost silver watch on May 4 in Dublin

This is a stainless steel Skagen watch with an unusual mesh strap. It is of high sentimental value as it is inscribed "To my little Editor" on the back. I thought I had it in my handbag leaving Drumcondra and heading to work in Sandyford last Friday morning but did not have it that evening. I could have lost it anywhere - I cannot figure out how I did. I take the Green Line Luas to Sandyford and was in a couple of shops that morning but have tried them and my gym and no sign. There would be a reward if I get it back!
