29mm by 23mm solid 18K yellow gold case, black leather strap, hand-wind mechanical movement, Swiss made, circa 1980s.
 
This watch was purchased from a reputable dealer in Europe; it keeps good time for everyday use, and starts running with a little shake. While the exact power reserve hasn't been tested, the watch runs for longer than a full day. It doesn't require a service but doing so may be beneficial.
 
As can be seen in the photos, this Piaget is in EXCELLENT condition, especially for its age. All parts (solid gold case, dial, hands, mechanical movement, beaded cabochon crown, genuine leather strap, solid gold buckle) are believed to be GENUINE Piaget. Box & papers not included.
