Description: Rolex Cellini 6663 Pre-owned Rolex Cellini ref 6663 (1991). Rolex has always used the Cellini as a platform for some of its more unusual design concepts. No Oyster cases or self-winding “Perpetual” movements here. Just the most exquisite materials and jewelry-forward designs. While the collection has recently taken on a more traditional dress-watch aesthetic, it was a different story decades ago. Watches were more ornate and retro.
