Audemars Piguet "Jumbo" Extra-Thin Openworked

Audemars Piguet's Royal Oak "Jumbo" Extra-Thin Openworked, reference 16204BA.OO.1240BA.01, has a 39 mm case in 18-carat yellow gold. The case measures a slim 8.1 mm thick, in keeping with the "Jumbo" Extra-Thin designation. A sapphire crystal covers the openworked dial, which lets the gold-toned bridges and gear train show through. Inside is the self-winding calibre 7124, skeletonised throughout so its finishing is visible from the front. The movement gives hours and minutes only, kept simple to let the open construction stand as the main feature. An 18-carat yellow gold bracelet closes with an AP folding clasp. Water resistance sits at 50 metres.
