Audemars Piguet Royal Oak Chronograph 25860ST.OO.1110ST.04 - "Cosmo Blue" Dial - Watch Only The Royal Oak Chronograph 25860ST is one of the most desirable configurations in the pre-current Royal Oak lineage - the deep "Cosmo Blue" petite tapisserie dial with gold-toned subdial rings giving it a depth and warmth that the later references moved away from.
