It had a left-side crown and right-side chronograph pushers. The Calibre 11 Chronomatic built on Buren’s ultra-thin Intramatic microrotor movement with a Dubois-Depraz chronograph module on top. Breitling and Hamilton completed the line-up. The company had already been experimenting with Buren’s microrotor automatic movements to develop a modular chronograph. He brought into the mix Buren, which made some of the world’s most compact automatic watches, and Dubois-Depraz, a specialist in converting basic movements into chronographs. The second was Caliber 11, developed under the watchful eye of Jack Heuer.

Seiko’s 6139 calibre was the first full rotor, vertical clutch, column-wheel controlled, automatic chronograph ever, with 17 jewels, a 30-minute counter and quick-set day-date complications, beating at 21,600 vph. Omega having lost its big chance, the race to produce the world’s first automatic chronograph fell to three competitors. Lemania had already produced a prototype automatic chronograph calibre in 1947, but it never left the factory Omega directors are said to have deemed the project superfluous. The solution was for the chronograph to modernize itself with automatic winding. By 1960, the hand-wound chronograph seemed like something from another era. The apogee of this era was undoubtedly the most legendary and celebrated hand-wound chronograph of them all: the Omega Speedmaster, which this year celebrates its 60th anniversary.Įven so, the Swiss industry experienced a massive decline in sales of chronograph watches in the late 1950s due to the ever increasing popularity of the automatic and waterproof watches now on offer. Legendary wrist chronographs were born, such as the Universal Genève Aero-Compax, the Navitimer and the Chronomat by Breitling, the Rolex 4113 split-seconds chronograph, Minerva chronographs with the 13-20CH calibre, Longines chronographs with the 13ZN calibre, and aviation chronographs from Hanhart, Urofa and, later, Breguet and others. Companies like Venus, Leonidas, Minerva, Martel, Excelsior-Park, Valjoux and Lemania produced outstanding chronograph calibres. Several names stand out from this first period, with productions that closely resemble what we know today. This would be the face of the chronograph. In 1932 Universal Genève added a second pusher at 4 o’clock for resetting. Breitling perfected the design in 1923 by separating the stop/start function from the reset function, through a combination of a crown and a single pusher at 2 o’clock. Integrating the stopwatch complication into existing calibres was extremely tricky, and so it wasn’t until 1913 that Longines produced the first wrist chronograph. By the 1870s, mechanical stopwatches were in general use on racetracks, at sporting events, and especially among artillery officers.
He created a chronograph for King Louis XVIII, although less complicated than the Compteur de Tierces.
The next step came from Nicolas Mathieu Rieussec of France in 1821. Louis Moinet began working on his Compteur de Tierces (literally “counter of thirds”, a term used to denote one sixtieth of a second in a pre-decimal age) in 1815 and completed it around a year later in 1816. A proliferation of stopwatches and chronographs followed.
