The 1916 Heuer Mikrograph made history by being the first stopwatch capable of timing to 1/100th of a second. Previously timing was only precise to 1/5th second. This breakthrough, thanks to the technical prowess and tenacity of Edouard Heuer, meant that scientists and sportsmen were able to explore new dimensions of precision and perfection. Heuer patented the system that secured this family-owned Swiss watch house a place in the history of watchmaking and precision timing. This year TAG Heuer has recreated the Mikrograph in a wristwatch with a very easy to read stopwatch function, making this the first wrist-worn stopwatch capable of measuring to 100th of a second. The smooth sweep of the large central blue hand follows a track on the outer edge of the dial allowing time to be read to the nearest 1/100th second without having to squint at a small sub-dial bristling with markings. The re-incarnation of this historical piece is presented in a rose gold Carrera case and only a limited edition of 150 will be produced. True to the original 1916 stopwatch, the dial features the original Heuer brand and blued steel hands, details that watch collectors will appreciate. The column-wheel chronograph can be stopped or started independently of the watch function. The movement has two separate balance wheels. The one corresponding to the chronograph oscillates 360,000 times an hour while the balance wheel associated with time keeping oscillates at a more normal rate of 28,800 times per hour. The automatic movement of the watch has a 42 hour power reserve and the chronograph can run for up to 90 minutes. The precision of the watch is certified by the COSC.
