Beautiful Vintage Marcasite Watch W/Heart Band.

Beautiful vintage marcasite watch with heart band. Some discoloration from wear; as shown in the last 2 pics before the videos, from wear & the knob is missing; as shown in the 3rd to last pic before video, but you can use pliers to pull out & set time. My wrist measures 6" & there's only a tiny bit of leeway moving back & forth.
