Audemars Piguet Royal Oak Offshore Chronograph 43 mm with Baguette-Cut Diamonds

The new 18-carat white gold Royal Oak Offshore Selfwinding Chronograph 43 mm versions entirely paved with baguette-cut diamonds complement the series of Audemars Piguet Royal Oak Offshore Gem-Set pieces unveiled early this year.

The two 43 mm white gold Royal Oak Offshore self-winding chronographs boast a case, bezel and dial entirely paved with baguette-cut diamonds. Even the black counters on the two dials have been set with baguettes arranged in a sunburst pattern, while the black inner bezel and black ceramic push-pieces add a subtle contrast.

The gemset 18-carat white gold case’s shimmering grey hues are magnified by the large polished bevels adorning the two timepieces.

The alternation of gemsetting and polished chamfers can also be admired on the curved push-piece guards. The double glare-proofed sapphire crystal, which is curved from 6 to 12 o’clock to integrate the ergonomic curvature of the bezel, provides a unique visual experience on the dial.

The counters’ horizontal arrangement – with the hour counter located at 3 o’clock, the small seconds at 6 and the minute counter at 9 o’clock – provides optimum readability.

The first model, which features a total of 230 stones (~19.2 carats), has a black rubber strap. The second timepiece comes with a bracelet entirely covered in baguette-cut diamonds.

Contrary to other 43 mm models in the Audemars Piguet Royal Oak Offshore collection, the strap and bracelet of the two gemset models are not interchangeable due to the baguette-cut setting on the case’s studs. The number of diamonds adorning each fully gem-set piece totals 646 baguettes (~48.9 carats).

AP Calibre 4409

These new Royal Oak Offshore references house the Audemars Piguet Calibre 4409, a new generation self-winding integrated chronograph movement.

This calibre comes with a high-end column wheel and a flyback function that enables to instantaneously restart the chronograph without stopping or resetting it first. It is also equipped with a vertical clutch system that prevents hands from jumping when the chronograph is started or stopped, as well as a patented zero resetting mechanism ensuring that each one of the counter hands seamlessly resets to zero.

Beating at a high frequency of 4 Hz (28,800 vibrations/hour), Calibre 4409 offers about 70 hours of power reserve.

The sapphire caseback reveals the collection’s dedicated blackened 22-carat pink gold oscillating weight and other components like chronograph hammers. Calibre 4409 features refined decorations on the caseback side such as Côtes de Genève, traits tirés, polished chamfers and circular graining.
