This year, Audemars Piguet introduced six new references in its Royal Oak Offshore Chronograph collection. They replace the previous ROO collection and appear in a new 42mm case size, compared to the previous 44mm case size of the most recent models. The original ROO, launched in 1993, was 42mm, and Audemars Piguet feels that size seems appropriate once again as watches are increasingly being scaled back. The new collection is more refined, with downsized, sculpted hour markers and faceted hands. The new pieces also indicate AP’s commitment to ceramic. The crowns and pushpieces are now ceramic instead of rubber. Most striking of all about the new ROO collection is the sapphire caseback, through which the movement can now be seen, including a 22k gold engraved rotor. New models include navy, black with red highlighting, all-grey, ivory and brown, and a stunning pink gold version.
