AUDEMARS PIGUET RELEASES NEW SHADES OF BLUE FOR THE ROYAL OAK PERPETUAL CALENDAR

The dial is adorned with new contrasting blue hues that engage with ambient light.

NEW SHADES OF BLUE

While the subdials and the inner bezel of the “Grande Tapisserie” dial encompass the iconic blue hue of the original Royal Oak, a colour referred to as “Night Blue, Cloud 50” in the Manufacture’s archives, the remaining surfaces are dressed with a lighter blue shade, offering an interesting contrast and play of light.

The topography of the dial incorporates four subdials granting a sense of equilibrium. The functions include a week indication, day, date, astronomical moon, month, leap year, hours and minutes.

STEEL OR PINK GOLD, BUT ALWAYS HAND-FINISHED

The 41 mm case of the Royal Oak Perpetual Calendar has a slender profile with a thickness of just 9.5 mm and is offered in two variants: stainless steel or 18-carat pink gold.

Both case options are hand-finished with satin-brushing and polished surfaces. They are paired with matching bracelets fitted with an AP folding clasp, while the chosen case material perfectly complements the blue dial tones and provides the wearer with a stylish means of self-expression.

THE SELFWINDING CALIBRE 5134

The selfwinding Calibre 5134 incorporates an intricate mechanism that draws upon the Manufacture’s savoir-faire.

It automatically takes into account the number of days in the month and correctly displays the prevailing date even in leap years. Assuming the watch is kept fully wound, the date will not require manual correction until 2100 to stay in line with the Gregorian calendar.*

By looking closely at the composition of the movement, the company’s watchmakers have created a slender calibre measuring just 4.3 mm in height. This has been achieved by re-arranging a number of components including the 22-carat openworked oscillating weight. The bulkiest part of the rotor is positioned to its outer edge which is recessed within a channel encircling the movement, thereby mitigating height. Likewise, a suspended barrel has provided a further means of reducing the movement’s thickness.

Visible through the sapphire caseback, Calibre 5134 incorporates refined finishing synonymous with Haute Horlogerie. This includes “Côtes de Genève,” circular graining, circular satin and polished chamfers throughout.

* The Gregorian calendar omits three leap years every 400 years to remain in line with solar time. This is achieved by omitting February 29 in the century years which number can be divided by 100, but not by 400. As a result, 2100 will not be a leap year and perpetual calendar mechanisms will have to be moved forward by one day.

“Born in Le Brassus, raised around the world.”
