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.
Arguably the best known dial color found on Royal Oak timepieces, the present watch features a “sapphire blue” dial according to the official Audemars Piguet nomenclature. However, even the greenest watch enthusiast knows the community calls it a different, very appropriate nickname: the “Yves Klein”. When the beauty and rarity of the "Sapphire Blue" dial merges with the collectability and historical appeal of a perpetual calendar Royal Oak, one knows without a doubt that one is in the presence of a wristwatch that is as eminently collectible as it is strikingly charming. Most importantly, research with the manufacture confirms that the "02"in the reference number corresponds to a “sapphire lacquered” dial which corresponds to this type of blue.
Offered in excellent condition of both case and dial, the present watch will not fail to satisfy the horological needs of the most demanding Royal Oak collectors.
