Measuring 39mm in diameter and just 8.1mm thick, the Royal Oak "Jumbo" Extra-Thin wears its legendary proportions with extraordinary opulence. The diamond-set 18-carat white gold case is fitted with a glareproofed sapphire crystal and a matching sapphire caseback, while water resistance is rated to 50 metres.
The 18-carat white gold dial is itself diamond-set, complemented by white gold applied hour-markers and Royal Oak hands finished with a luminescent coating. The stone count is precise: 384 brilliant-cut diamonds totalling approximately 2.44 carats adorn the dial alone.
Continuing the full-diamond presentation, the 18-carat white gold bracelet — secured by an AP folding clasp — contributes to a combined case and bracelet setting of 1,102 brilliant-cut diamonds weighing approximately 7.09 carats. Reference 15202BC.ZZ.1241BC.01 is one of the most jewelled expressions of Gerald Genta's enduring Royal Oak design.
