Santa Anita watch, collector's souvenir

Santa Anita jockey silks Vintage collectible wrist watch. It has a stem for winding so probably no battery, but at the moment I don't want to risk pulling the stem out to wind it. So this is being sold only as a collector's item and not as an actual timepiece. It may very well work but no guarantees here. Right now, it's not running. Some visible corrosion that can probably be cleaned up. It does not show so if you want to wear it, no one will see any damage. Famous jockey silks from late 70's and 80's, including Fred Hooper. Black band. This was a limited edition collection. Unisex but I had to choose one😆 Smoke-free home. Happy to answer any questions.
