Introducing a leap year indicator to Audemars Piguet’s Royal Oak Perpetual Calendar, the reference 25820 was launched in 1996 and remained in production until 2013. The complete count numbers 628 pieces in steel, 107 pieces in yellow gold, 74 pieces in platinum, 11 in pink gold, 378 in steel/platinum, 15 in tantalum/yellow gold, 9 in tantalum/platinum, and 13 in tantalum/pink gold were produced, for a grand total of 1,235 examples. Of those 74 pieces in platinum, research shows that only 12 were ever fitted with the elusive ‘Tuscan’ dial, and to our knowledge only one example of this configuration has ever been offered publicly.

The flawless, arresting, and dynamic “Tuscan” dial draws its name from the unique texture of the dial, reminiscent of the characteristic finishing of the Italian region’s buildings. When examined closely, one will find that no two dials are exactly alike. The fine and delicate ridges on the dial catch the light perfectly, and can change in tone depending on the angle. The silver printing on the dial, rather than white, is a flawless design choice on the part of Audemars Piguet, perfectly complementing the luxurious platinum case.

Recently serviced by the manufacture, the present platinum Royal Oak perpetual calendar in platinum retains its service stickers to the caseback and bracelet. In superb condition, it is offered with its full complement of original accessories; a stunning and pristine example for the collector in pursuit of the rarest of the rare.
