The beautiful timepiece is in phenomenal condition for the age. It comes fitted with a generic leather brown strap but does come with the original black alligator leather strap (not in good shape). The case is very sharp, and all numbers are crisp and legible. These are the Rolex pin buckle clasp that are gold plated. I replaced the pin in the buckle. Mechanically the watch is functioning as it should. Serial numbers & names are blurred in photos only for privacy reasons.
