Audemars Piguet "Jumbo" Extra-Thin Openworked

Audemars Piguet's Royal Oak "Jumbo" Extra-Thin Openworked, reference 16204BC.OO.1240BC.01, has a 39 mm case in white gold. The case measures 8.1 mm thick, keeping the extra-thin profile the Jumbo line is known for. A sapphire crystal covers the openworked dial, which exposes the movement's bridges and gear trains on both faces. Inside is the self-winding calibre 7124, hand-finished and skeletonised so its architecture is visible from the front and through the display side. The watch shows hours and minutes only, with no clutter to distract from the open construction. It comes on a white gold bracelet fitted with an AP folding clasp, matching the case in tone and finish. The clasp secures a case rated to 50 metres of water resistance.
