They feature a particular countdown pre-setted system that is activated by the chronograph and displays the remaining time from SET to START, usually with analog numbers or bright-colored slots to ease the read. Not less important, these chronographs are used by skippers to calculate, in the minutes before the start, the right side to start on the base of the start line and wind direction. Regatta chronographs S.Song Watches Regatta Yachttimers A distinctive feature is in the position of the pusher, that can be found at 2, 4 or, in some cases, in the crown at 3 o’clock. The monopusher chronograph features a single pusher that, in sequence, allows to operate all the functions of start, stop and reset that are usually managed through two different pushers.

Different types of chronographsĬhronographs are important calculation tools that need to provide the highest precision possible. The best mechanism surely is the column wheel with vertical clutch, while the most budget-friendly is the cam shunt with lateral clutch, lacking in precision because of the “jump” caused by the joining of running seconds and chronograph’s gears. The number of components involved is similar to a column-wheel mechanism but requires less building precision and lower manufacturing and servicing costs. This system makes the engagement of the chronograph really smooth and needs for less pressure compared to cams.Ī cam shunt works thanks to cam-operated levers. It works via a Column Wheel, a cylindrical component with six trapezoidal “columns” on the top, used to manage the chronograph’s different levers related to the functions. It’s considered to be the best shunt system, except being very technically advanced, rises the prestige and the collectors’ praise because of its manufacturing complexity. The real revolution came in the 30s, when the first wrist chronographs were patented, adding a module to the mechanism capable to operate independently the start, stop and reset functions.

However, the term “ chronographe” was introduced a few years later by Nicolas-Mathieu Rieussec that patented a system where a little ink tank was fitted into the measuring hand, recording the time interval on a white dial, allowing it to be measured.Īctually, the name “chronograph”, as explained to us by the Director of Brand Heritage of Omega, Petros Protopapas, is a common mistake that derives from the invention mentioned above. The first chronograph in history, the “Thirds counter”, was created by Louis Moinet in 1816 and was the first pocket watch with a central hand capable to rotate in one minute and to be activated, stopped and resetted with a pusher.
