Production of the second-type 26022 continued until 2012 when the collection was relaunched in a 41mm case (Ref. 25860, with luminous baton indexes designed by Gérald Genta, a luminous triangular index at 12 o’clock, and small rectangular markers at the 3, 6 and 9 o’clock positions. With this modernisation, the designation of reference 26022 did not change, but the dial design was modified – reference 26022 of the latter period has a dial of the second type, as the present example, which generally reminds one of the original design of the Royal Oak Chronograph Ref. 26300 (the replacement of a two-part case with a three-part one).
ROYAL OAK CHRONOGRAPH UPGRADE
In 2008, Audemars Piguet made an upgrade to reference 26022, most probably technically similar to the changeover from Ref. The first, early type of reference 26022 has a specific dial design with square luminous hour markers. 26022BA, 26022OR, and 26022BC, respectively, were produced until at least 2012, and are divided into two types.

Multiple versions of model 26022 with yellow gold, rose gold, and white gold versions designated as Refs. 26022OR example dated 2005, while Phillips mentions 2004 as the launch date). However, there are reasons to believe that the production of reference 26022 began several years earlier, perhaps as far back as 2005 (Ineichen Auctioneers sold in 2022 a Ref. Reference 26022 is widely accepted as a precious metal version of the second-generation Royal Oak Chronograph Ref. The present reference 26022 was produced by Audemars Piguet as a precious-metal Royal Oak Chronograph on either a leather or rubber strap, most likely launched circa 2004.
