Celebrating its 20th anniversary in style, the Royal Oak Chronograph by Audemars Piguet enjoys the best of two worlds: a long history of chronograph wristwatches that the brand has been making for over 80 years, and, as a member of the Royal Oak family, the iconic octagonal bezel with eight hexagonal screws design. To celebrate, the brand is launching a set of new Royal Oak Chronographs with two-tone dials, inspired by a 2008 design, and a smattering of subtle aesthetic changes.

There are seven new models in all. Their dials recall vintage examples from the 1930s to 1960s, with subdial colors that contrast the color of the main dials. Among the changes are larger chronograph counters positioned at 9 o’clock and 3 o’clock, shorter but wider applied hour-markers, Royal Oak hands with additional luminescent coating for better readability of the hour, and new typeset and transfers. The date window is located between four and five o’clock.

The new Audemars Piguet Royal Oak Chronographs include four versions in rose gold, available on either a matching rose gold bracelet or an alligator strap and with a choice of brown or blue dials adorned with the “Grand Tapisserie” motif that is a hallmark of the Royal Oak collection. The steel versions of the watch are offered with a choice of “Grande Tapisserie” dials in black, silver, or blue and fitted with stainless steel bracelets.

The watches all equipped with the self-winding Calibre 2385 with a power reserve of 40 hours and functions of chronograph, hours, minutes, small seconds at 6 o’clock and date, the Audemars Piguet Royal Oak Chronograph comes in a 41 mm x 11 mm case with glareproofed sapphire crystal and screw-locked crown for water resistance to 50 meters. The prices range from $29,300 to $56,600.
