Royal Oak Concept Laptimer Michael Schumacher

Description

Video THE ROYAL OAK CONCEPT LAPTIMER WHY IS UNIQUE - AND HOW IT WORKS \tTraditionally, short circuit motor racing is timed from the track side with two or more hand-held stop watches. As one lap is completed, the first watch is stopped and the second is started. \tIf a split-second chronograph is used, it is to measure intermediate times only. When the chronograph is started, both second hands run simultaneously. When the split-second pushpiece is pressed, one hand stops allowing the reading of intermediate time, while the second hand keeps going. By again pressing the split-second pushpiece, the first hand will be resynchronized with the second and both will continue the timing. \tThe Audemars Piguet Royal Oak Concept Laptimer Michael Schumacher, however, features a single chronograph driving two central hands which can be controlled independently via three pushpieces - the first sited at the conventional two o’clock position to start and stop the chronograph; the second sited at the four o’clock position to reset the chronograph, and the all-important third pushpiece sited at the nine o’clock position. \tThis third pushpiece makes it possible to simultaneously stop either of the two chronograph hands, while returning the other to zero and restarting it - meaning that, while the time of the most recent lap is being noted down, timing of the next lap is already underway. The watch therefore negates the need for two or more hand-held timing devices, streamlining the operation within a single wrist chronograph. \tAlternatively, the watch can keep a certain lap time as reference, stopping one hand with the laptimer button, and using the flyback function on the other chronograph hand with the pusher at 4 o’clock to restart the measurement of each new lap. \tFinally, the timepiece can be used as a "standard" flyback chronograph with both hands running together in parallel. \tThe Royal Oak Concept Laptimer Michael Schumacher is the world’s first mechanical chronograph with alternating consecutive lap timing and flyback function specifically designed and engineered for continuous action and relentless precision in timing laps on the racetrack.\t THE INNOVATIONS \tDeveloped at the design and technical department of Audemars Piguet, the Royal Oak Concept Laptimer Michael Schumacher features a pending patent covering its unique functionality, which is based on a mechanism incorporating no fewer than three column wheels. \tOne column wheel, located at the six o’clock position, controls the chronograph sequence, while the two at the 12 o’clock position control the complex laptimer sequence. \tThe gear train is driven by two mainspring barrels set in parallel which provide double of power reserve - and, to ensure exceptionally smooth operation the watch features specially developed conical gear teeth which mesh seamlessly and accurately at all points in the movement’s cycle for a perfectly linear torque transmission. A new oscillating wheel coupling mechanism has been developed for jerk-free action when the chronograph is stopped or started. \tSince the new Audemars Piguet 2923 calibre operates at a frequency of 4 Hertz = 28,800 vibrations/hour and features a variable-inertia balance wheel, it is capable of recording times down to one-eighth of a second. \tDue to the complexity of the movement’s construction, it contains several unusually long and slim components which would not operate satisfactorily using traditional lubricating methods. As a result, the engineers at Audemars Piguet chose solid lubricants which will not deteriorate easily and which will remain consistent and offer exceptional longevity.\t THE DESIGN \tAs seen on previous Audemars Piguet Concept watches, the Royal Oak Concept Laptimer Michael Schumacher features a 44 mm case made from forged carbon.\tThe bezel, case edges and caseback, meanwhile, are made from titanium and the pushpieces from ceramic and pink gold. \tThe blackened openworked dial, like the back of the watch, is protected by a glare- proofed sapphire crystal with the watch being supplied on a black rubber strap with a titanium AP clasp. \tClose examination of the Royal Oak Concept Laptimer Michael Schumacher also reveals subtle references to the man who inspired it - seven stars, for example, are marked on the left side of the case in honour of Michael Schumacher’s seven F1 World Championship titles, and his celebrated ‘MS’ monogram appears on the laptimer pushpiece. Finally, in honour of his extraordinary career, the Royal Oak Concept Laptimer Michael Schumacher will be made available in a strictly limited edition of 221 pieces in recognition of the number of F1 World Championship point-winning races in which he competed.\t
