“We are proud to introduce Audemars Piguet’s first selfwinding flyback chronograph equipped with a split-seconds mechanism. This classic complication has been entirely rethought to fit in a highly contemporary sports watch offering optimum reliability for the present day. This watch was made possible thanks to the collaborative work of our different teams, specialized in the production of highly complicated mechanims.” Lucas Raggi Research and Development Director, Audemars Piguet
A FUTURISTIC CASE PLAYING WITH DEPTH, FINISHING AND LIGHT
Audemars Piguet continues to evolve the Royal Oak Concept with the addition of an innovative complication blending ergonomics with the collection’s bold aesthetic looks. This timepiece required extensive R&D engineering, pushing the teams’ technological expertise further.

In addition to introducing a new
43 mm case size, the titanium watch boasts a multifaceted design playing with contrasts and light. The case’s elaborate architecture necessitated complex programming and manufacturing processes to strike the right balance between ergonomics and ultramodern design. The case and bezel are slightly curved to match the natural shape of the wrist, making it comfortable to wear despite the watch’s generous size.

The sandblasted case is topped off with the Manufacture’s trademark satin-brushed octagonal bezel, whose rounded outline is highlighted by polished chamfers. The combination of satin-brushed, sandblasted and polished surfaces furthers the watch’s textured look, while providing an endless play of light.

Three-dimensional push-piece guards brazenly secure the pushers at 2, 4 and 9 o’clock, each finished with the same juxtaposition of sandblasting, satin brushing and polished chamfers as seen on the case.
“This selfwinding split-seconds chronograph has been designed to the extreme inside and out. Integrated into the futuristic Royal Oak Concept case, this complication has reached a level of technical complexity never achieved before.” Anne-Gaëlle Quinet Head of Complications, Audemars Piguet
A TWO-TONE OPENWORKED DIAL DISPLAY
Conceived like a movement bridge, the openworked dial gives a glimpse of the complicated micro-mechanics ticking within. The rounded openings have been cut out from a single German silver plate, finished with sandblasted black PVD and polished rhodium-toned bevels. This contrast confers depth and light to this sporty and architectural timepiece, which is further enhanced by the absence of a logo on the dial.

White gold hands and hour-markers, complemented with white transferred numerals spread across the dial, accentuate the watch’s two-tone aesthetic. In addition, the hour-markers, hands, counters, large date and GMT day/night disc feature luminescent coating for optimum visibility in the dark. Red and yellow accents, respectively marking the chronograph and GMT functions, add a subtle, yet vivid touch of colour. A black inner bezel, on which a white tachymeter scale has been printed, completes the watch’s overall design.
A HIGH-TECH SPLIT-SECONDS, FLYBACK CHRONOGRAPH
Ultra-contemporary inside and out, the new timepiece premieres the selfwinding Calibre 4407 – a feat of mechanical and industrial engineering that combines flyback chronograph, split seconds, GMT function and large date into the highly stylised case design of the Royal Oak Concept collection. The first of its kind to be produced in a series at Audemars Piguet, it is based on the Manufacture’s latest generation integrated flyback chronograph movement, Calibre 4401, which was launched in 2019 with the Code 11.59 by Audemars Piguet collection.

Unlike a regular chronograph, the flyback function allows the wearer to reset and restart the chronograph without having to stop it first. The column wheel works with a vertical clutch system. When starting or stopping the chronograph, the hands respond accordingly without any hint of jumping. Furthermore, a patented zero resetting mechanism ensures that both chronograph and split-seconds hands instantaneously reset to zero.

The split-seconds mechanism enables to measure intermediate time intervals thanks to the addition of a split-seconds hand that can be stopped independently of the chronograph hand when the dedicated pusher is activated. When the latter is pressed again, it catches up to the running hand to continue their journey together around the dial, in perfect synchrony. The action can be repeated at will. Located at 9 o’clock, the push-piece subtly nods to the
Royal Oak Concept Laptimer (2015) – the first mechanical watch capable of measuring consecutive lap times on the racetrack developed in collaboration with
Michael Schumacher.

To reduce the movement’s height, the split-seconds mechanism has been integrated within the thickness of the semi-peripheral rotor’s ball bearing and is now visible through the sapphire caseback like in pocket watches and hand-wound wristwatches. Usually hidden from view in selfwinding watches, the split-seconds wheel and two actuating clamps can be admired at the centre of the platinum oscillating weight, under the X-shaped bridge holding the mechanism in place.

Although incorporating high-tech features,
Calibre 4407 continues to uphold fine watchmaking traditions and presents elegant Haute Horlogerie decorations, including sandblasting, circular satin, circular graining and polished chamfers, all visible through the sapphire caseback.
“We currently have 18 movements in development across collections. The launch of our new Royal Oak Concept Split Seconds Chronograph GMT Large Date is part of our ongoing effort to build the future of AP.” - François-Henry Bennahmias CEO, Audemars Piguet
A PIONEERING MOVEMENT
Based on the in-house chronograph Calibre 4401 released in 2019 in the Code 11.59 by Audemars Piguet collection, the Calibre 4407 has been deeply reengineered to improve its energy management in order to allow the addition of the split seconds mechanism.

In addition of this, a new oscillator has been developed which features a
Breguet overcoil, whose sharply curved outer end ensures the concentric development of the balance spring for increased accuracy
A NEW STYLISED INTERCHANGEABLE STRAP
The new sporty timepiece premieres the first interchangeable strap of the Royal Oak Concept collection. The interchangeability system has been directly integrated into both the case and the triple-blade folding clasp to enable the wearer to change strap with a quick click and release. The system also provides optimum security when the watch is worn.

The design of the new black interchangeable rubber strap blends in with the facets of the case. The bevels on the case sides extend onto the strap, providing a seamless continuity between the two components. Furthermore, the strap is decorated with symmetrical inserts in grey hues that echo the multidimensional, two-tone aesthetics of both the case and the dial. The timepiece comes with a second all-black interchangeable rubber strap for wearers to style up their watch depending on their mood.
Two additional black rubber straps contrasted with yellow or red accents will be available in boutiques as part of the interchangeable strap assortment for the new
Royal Oak Concept 43 mm diameter.
WHEN RARITY MEETS HIGH TECHNOLOGY
Launched in 2002 to celebrate the Royal Oak’s 30th anniversary, the Royal Oak Concept established an entirely new aesthetic for 21st-century Haute Horlogerie. For the occasion, Audemars Piguet released a 150-piece limited edition inspired by Concept cars that combined titanium with Alacrite 602, a light yet highly resistant alloy mainly used in the aeronautical industry. While the bezel retained the Royal Oak’s trademark octagonal shape, the massive rounded 44 mm case brought this timepiece to new horizons. To complement the case’s futuristic aesthetic, the dial exposed the state-of-the-art hand-wound mechanism, while providing innovative functions: a push-piece serves as a function selector (for winding and setting the time) and a dynamograph displays the mainspring torque.

A linear power-reserve display is indicated thanks to the calculation of the number of turns of the barrel, along a scale of 0 to 12, with each turn representing six hours of autonomy. The tourbillon cage and its shock-absorbing bridge was also visible at 9 o’clock and the timepiece was fitted with a Kevlar strap. Although conceived as a concept watch that wasn’t intended to for commercialization, a small series was made to celebrate the
20th anniversary of the model. Four years later, a new interpretation was unveiled in carbon, marking the birth of the
Royal Oak Concept collection. Since then, the
Royal Oak Concept has pushed the limits of Haute Horlogerie craftsmanship by blending high technology mechanisms with avant-garde designs.

This year, the
Royal Oak Concept reinterprets the split-seconds chronograph for the present day. This complication is the last family of classical complications that was introduced in the history of watchmaking. It was born at a time when the world was in full acceleration and speed was everything, both in terms of industrialization and the diffusion of competitive sports. Its origin is the measurement of performance.
Of the
1,625 watches produced in the
1880s and
1890s,
625 included a chronograph, of which
299 were equipped with a split-seconds hand. The majority of chronograph pocket watches released thereafter and through the
21st century continued to feature a split-seconds hand.

However, this complication was immensely rare in the Manufacture’s chronograph wristwatch offering in the
20th century. Only one example is documented before
1996. Records show that this
unique example was sold by
Audemars Piguet to
New York retailer Roehrich on April 14,
1949 and now belongs to a prestigious private collection. The
35 mm yellow gold wristwatch is powered by the
Calibre 13VZAH. The split-seconds mechanism was added following a special request received after production had started. The archives mention an additional split-seconds movement, made in
1946, yet it is unlikely that it was ever cased up and sold.

In
1996, the split-seconds chronograph made its come back, this time miniaturised to equip the first
Audemars Piguet Grande Complication wristwatch presented in a round case. This model combined the split-seconds chronograph with the perpetual calendar and the minute repeater as per
Audemars Piguet Grande Complication tradition. The first
Royal Oak Grande Complication followed in
1997, while the first
Royal Oak Offshore Grande Complication saw the light of day in
2013 on the occasion of the sports watch’s
20th anniversary.
Click, to see the large size. ▶ BIG FOTO The miniaturisation of the split-seconds mechanism also led
Audemars Piguet to explore other technical horizons for the chronograph function. In
2015, the Manufacture released the patented
Royal Oak Concept Laptimer in collaboration with
Michael Schumacher.

Endowed with a flyback system with two successive and alternating flyback chronograph hands, this avant-garde watch allowed the measurement of consecutive lap times on the racetrack thanks to a single chronograph driving two central sweep-seconds hands controlled independently via three push-pieces. This watch represents a world first as such time intervals could only be measured digitally beforehand.

Following in the footsteps of this highly complicated timepiece, the split-seconds function joins the Royal Oak Concept collection this year, paving the way for a new generation of advanced split-seconds mechanisms independent of the Manufacture’s Grande Complication production and merging engineering, technology and watchmaking artisanship.
“Born in Le Brassus, raised around the world.”
