Complications and ultra-thin models: two time-honoured Audemars Piguet specialties meet in the Royal Oak RD#2. It has taken five years to develop the new ultra-thin 5133 caliber with perpetual calendar.
The challenge has been to re-engineer a three-storey movement into a single level, making it ultra-thin while combining and re-arranging functions to boost ergonomy, efficiency and robustness. This patented system features a recordshattering 2.89 mm central rotor. At just 6.30 mm, the redesigned case shaves almost 2 mm off the Royal Oak Extra-Thin Jumbo, making the Royal Oak RD#2 the thinnest selfwinding perpetual calendar on the market today.
Technical Specifications:
The case, in platinum, measures 41mm x 6.3mm. It has an AR-coated sapphire crystal, a sapphire display back, and it is water resistant to 20 meters.
Movement is the Swiss automatic Audemars Piguet in-house caliber 5133 with 37 jewels, 19,800 vph and a power reserve of 40 hours. Functions are: hours, minutes, perpetual calendar with day, date, astronomical moon, month, leap year, and night and day indication.
It has a blue dial with Grande Tapisserie pattern, blue counters, white gold applied hour-markers and Royal Oak hands with luminescent coating.
It comes on a platinum bracelet with AP folding clasp.
Thanks.
