New Release: Audemars Piguet Royal Oak RD#2 Perpetual Calendar Ultra-Thin

Thin, thinner, thinnest: The latest record breaker from Audemars Piguet
by Chelsey Chen on January 15, 2018

The 12 o’clock moon phase of the new ultra-thin prototype pays homage to the Company’s first perpetual calendar wristwatch that was introduced in year 1955.

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 calibre 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 record shattering 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 self-winding perpetual calendar on the market today.

Improved readability with expanded counters and a night and day indication.


Thinnest ever, but no compromise on quality: 40-hour power reserve, and same frequency (2.75 Hz / 19’800 vibrations per hour) as calibre 5134.


950 platinum case and bracelet with “Grande Tapisserie” pattern blue dial.
