2012 is an important year for Audemars Piguet, marking the 40th anniversary of the Royal Oak. The new products presented at the 2012 SIHH included this absolutely beautiful extra-thin tourbillon, the Openworked Extra-Thin Royal Oak Tourbillon.
The design seems to downplay the complexity of the movement, creating a dial which, when compared to the Openworked Extra-Thin Royal Oak limited edition, has a unique style, based on the classic Royal Oak design. The bezel has eight polished screws in white gold, with the corresponding bolts visible on the back, and the tapering bracelet corresponds to the Royal Oak pattern, seamlessly integrated with the case, with progressively narrower links. The new features of this anniversary model begin with the case in platinum, 41 mm in diameter, the first of this size in the range. The new Calibre 2924, with 216 parts, is an extra-thin manually wound tourbillon movement made in-house. At 4.46 mm thickness, it is one of the thinnest tourbillon movements, and it provides a 70-hour power reserve. The skeletonized dial creates an effect of depth by means of the anthracite finish, which contrasts with the yellow gold barrel, gear trains and balance.
The case is water-resistant to 50 metres. The sapphire crystal caseback provides another view of the movement, with a small power reserve indicator also on the back. The Royal Oak hands and hour-markers are in white gold with luminescent coating.
This is not a watch for everyone: in fact, just for 40 people. The limited edition corresponds to the anniversary of the Royal Oak. This makes it a collector's piece, and possibly an investment opportunity. Time will tell, as they say.
