You are buying a nice Eikon women’s quartz wristwatch with an adjustable white snakeskin-like leather cuff watchband.
The 7/8" watch appears to be in excellent condition, but will need a battery. The dial is marked “Eikon QUARTZ”. The back of the watch is marked “STAINLESS STEEL BACK SINGAPORE MOVT BASE METAL BEZEL” (see photos). The adjustable snakeskin-like leather cuff watchband is 3/8” wide and will adjust to fit most any wrist.
This would make a great addition to your own vintage watch collection or make a great gift for someone who collects vintage watches.
