World First: TAG Heuer introduces the first ever column wheel integrated mechanical chronograph displaying the 1/100th of a second with a striking central hand allowing an easy reading: the Heuer Carrera Mikrograph 1/100th Second Chronograph. Entirely designed, patented, developed and manufactured in La Chaux-De-Fonds, “TAG Heuer Haute Horlogerie” workshop also crafting the Monaco V4, this new major innovation from TAG Heuer confirms the company 150 years leadership in mastering ultimate accuracy, speed and high complexity mechanical movements.
5 years only after the revolutionary Calibre 360 Chronograph, TAG Heuer literally re-invents the high frequency dual assortment mechanical movements and pays a tribute to the legendary Heuer Mikrograph stopwatch of 1916 which made history for more than 50 years in timing high speed sports with its 25 and 50 hertz frequencies.
With 2 assortments, 62 jewels and 396 components, the Heuer Carrera Mikrograph 1/100th Second Chronograph is new a masterpiece of “Haute Horlogerie Suisse” setting a new milestone in grandes complications.
Like the Calibre 360, the Heuer Carrera Mikrograph 1/100th Second Chronograph features two different balance wheels, with separate escapements and transmission systems that allow to engage the stopwatch performance without interference to the watch movement.
However, unlike the Calibre 360 which was modular, the new Mikrograph 1/100th is a fully integrated COSC certified chronograph with a column wheel system. It comprises a balance wheel for the watch moving at 4 hertz, 28’800 vibrations per hour, with a 42-hour power reserve; for the stopwatch, the high frequency Swiss balance wheel oscillates at 50 hertz, 360’000 vibrations per hour, with a 90-minute power reserve, displaying this 1/100th of a second with the central chronograph hand. A transparent sapphire crystal case back allows a direct and stunning view of the two “hearts” beating at different speeds and facing each other at the bottom of the complex movement endowed with sophisticated Côte de Genève finishes.
TAG Heuer’s timekeeping heritage is peerless. It is fuelled by the distinction between just fractions of a second, when the performance of speed-driven professionals is at stake.
In 1916, TAG Heuer developed the Mikrograph, the first sports stopwatch accurate to 1/50th and 1/100th of a second when other timing instruments could only measure to the nearest 1/5th of a second. This technical innovation changed the future of racing events management, by gaining greater accuracy of a second – a mere moment that can count for everything between striving professionals. This groundbreaking core technology catapulted Heuer ahead as official timekeeper to the world’s most prominent competitive sporting events ever since.
Available in a rose gold limited edition of 150 timepieces only, the new Heuer Carrera Mikrograph 1/100th Second Chronograph brings this original stopwatch innovation to the wrists of modern motor-racing enthusiasts who seek ultimate precision. Until now, the wristwatch and stopwatch were separate instruments because of their differing performance objectives: the wristwatch is like a marathon runner, slow but with endurance, while the stopwatch is like a sprinter, fast but in bursts of activity. If they drew upon the same gear for their differing intensities, such a traditional chronograph movement would wear quickly.
With the Heuer Carrera Mikrograph 1/100th Second Chronograph limited edition, TAG Heuer celebrates in style “150 years of mastering speed”.

Essential technical elements that make this timepiece different:
– First chronograph with a central 100th-of-a-second hand turning one revolution per second and 100 jumps per second (3 times faster than on the historical Heuer model). There is no visible tremor during rotation.
– Dual control system: one for chronograph functions and one for setting watch time. It’s the first 100th of a second wrist-worn stopwatch.
– Extremely easy-to-read chronograph scale on the outside edge of the dial indicating tenths and hundreds of a second.
– Chronograph control with column wheel.
– Unlike a conventional chronograph, the time base is not dependent on the watch (hence the name “stopwatch”). Chronograph functions can be start or stopped independently of watch functions.
– The chronograph’s power reserve is independent of the watch’s (two separated cylinders).
– Automatic winding of the watch by means of a circular oscillating weight. Chronograph winding is done manually (once is 90-minute power reserve is depleted). Winding the chronograph also winds the watch — both barrels are wound at the same time.
– Chronograph power reserve display by full scale of 120° (the 90-minute-power reserve on a scale from 0 to 100%).
– Chronograph second counter at 6 o’clock.
– Chronograph minute counter at 3 o’clock.
– Small seconds counter at 9 o’clock.
– The wide spacing of the counters with respect to the centre makes for excellent readability.
– Semi-perpetual date window at 6 o’clock with rapid date correction with crown in middle position.
– 42-hour power reserve for the watch and 90-minute power reserve for the chronograph.
– The two balance wheels (4Hz clock and 50Hz chronograph) are visible through the open case back.
– The stop second enables watch time to be set to the nearest second.
