That's a beauty!!! I love the case, Wadsworth made some very ornate cases for Hamiltons, Benrus, Elgins and other manufacturers back in the day. I would send it to Mark at his shop in Kane PA, you'll pay $20.00 for shipping but he's really good with vintage watches.
WWW.THE WATCHDORTOR.COM. I've lost count of how many vintage watches he's serviced for me. You have a fantastic heirloom there, get it serviced and enjoy a nice dress watch.
