Until now, the tag heuer carrera mikrograph 1/100th – brown version replica watch 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.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.

Like the Calibre 360, the tag heuer carrera mikrograph replica features two different balance wheels, with separate escapements and transmission systems that allow to engage the stopwatch performance without interference to the watch movement. 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. 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.

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.

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.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 tag heuer replica watches.
