Rolex Daytona Yellow Gold Inverted Diamond Dial 16528 Watch
A true masterpiece of vintage horology and an immense collector’s prize, the Rolex Cosmograph Daytona reference 16528 with the “Inverted Diamond Dial” is an incredibly rare and historically significant timepiece. This model, from the first series of automatic Daytonas, is distinguished by its unique and highly coveted dial. Its “inverted” name comes from a specific font characteristic of early production runs: the “6” on the chronograph sub-dial at the 6 o’clock position is turned upside down. This detail, combined with the watch’s diamond-set hour markers, makes it a rare and visually distinctive variant.
