Audemars Piguet "Jumbo" Extra-Thin

Audemars Piguet's Royal Oak "Jumbo" Extra-Thin, reference 15202ST.OO.1240ST.01.A, has a 39 mm steel case. The case measures just 8.1 mm thick, a defining trait of this line. A sapphire crystal covers the blue dial, which carries a date window. Inside is the self-winding calibre 2121, one of the thinnest automatic movements Audemars Piguet uses. The movement drives hours, minutes and date with no other complications, keeping the layout clean. A steel bracelet with an AP folding clasp completes the watch. Water resistance reaches 50 metres, modest but standard for a dress watch of this type.
