Audemars Piguet has launched new Royal Oak Perpetual Calendar models with blue dial. Available in a choice of stainless steel or 18 carat pink gold case, this new watches feature an eye-catching dial adorned with new contrasting blue hues that engage with ambient light.
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 sub-dials granting a sense of equilibrium. The functions include a week indication, day, date, astronomical moon, month, leap year, hours and minutes.
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 self-winding Perpetual Calendar Calibre 5134 automatically takes into account the number of days in the month and correctly displays the prevailing date even in leap years. It requires a manual correction of date only in 2100 to stay in line with the Gregorian calendar.
The slenderness of this 4.3 mm thick calibre has been achieved by re-arranging a number of components including the 22-carat open-worked 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 highlights haute-horlogerie finishing techniques like “Côtes de Genève,” circular graining, circular satin and polished chamfers throughout.
