The history of the Calibre 11

Starts at the end of 1965. As Büren had pioneered the production of micro-rotor movements, Gérald Dubois (of Dépraz & Co., a chronograph specialist) figured out that these would be thin enough to be the base for a modular chronograph movement. Dubois contacts Hans Kocher of Büren Watch Co. SA. In need of commercial partners, they manage to convince first Jack Heuer and then Willy Breitling to support the project. On February 2nd, 1966, an agreement is signed. The four-party Chronomatic consortium is born, including two rival brands teaming up to develop their own automatic chronograph. For confidentiality purposes, the development is code-named Project 99.

 The convention signed on February 2, 1966, between Dépraz & Co., Heuer-Léonidas SA and Léon Breitling SA. The partners asked Büren Watch Co. to build the blanks and the automatic movement of an automatic chronograph, the basic execution of which is designated by calibre No. 111. They have an exclusive right to use this calibre. They plan to have Dépraz develop and manufacture the chronograph mechanism to equip this calibre.

Büren is in charge of the base calibre. Dépraz of the chronograph mechanism. Three brands – Heuer, Breitling and Hamilton (who acquired Buren during the development process) – will fit the movement inside their watches. A patent application for the Calibre 11 is filed in September 1967. At the end of 1968, about 100 pre-production movements are assembled in prevision of the 1969 Basel fair. On March 3rd 1969, the movement is officially presented, simultaneously in New York and Geneva. A month later, the three brands present their first chronographs at the 1969 Basel fair. With the practicality and comfort of automatic winding, the chronograph becomes a staple of motorsport… the Calibre 11 is used to power iconic watches by Heuer (Carrera, Monaco, Autavia), Breitling (Chrono-Matic) and Hamilton (Fontainebleau). And later by other brands such as Bulova, Kelek, Zodiac, Elgin, Stowa…

 So, who won the race?

Zenith’s automatic chronograph was the first to be unveiled to the world. It was presented during a press conference in January 1969 and christened El Primero (“the first” in Spanish). The reality is a bit more complex. There are endless debates about which was the first automatic chronograph, as both the Seiko and the Chronomatic movements were announced later the same year. What’s more, El Primero was not the first to hit the market. But the controversy about who came first doesn’t really matter anymore… what is important is the impact that these movements had on watchmaking history. Since then, the automatic chronograph has remained one of the most popular complications.

THE CALIBRE 11

The Calibre 11 is a 17-jewel modular chronograph measuring 31mm x 7.7mm. This modular architecture implies first a base movement, a micro-rotor automatic calibre made by Büren, in charge of the timekeeping part. Beating at 19,800 vibrations per hour, it boasted 42 hours of power reserve. Manufactured by Dépraz, the lever chronograph module is assembled on the backside of the base movement. This movement has a bi-compax display, with a 30-minute counter at 3 o’clock and a 12-hour counter at 9 o’clock – no running seconds sub-dial. The date is indicated at 6 o’clock. The unusual crown position, at 9 o’clock at the opposite of the chronograph pushers, is a signature feature of the movement.

 THE CALIBRE 11 AND ITS EVOLUTIONS

Like most movements, the Calibre 11 has been optimized several times over its lifetime. As early as 1969, a barrel spring providing less torque is used. The date jump mechanism is adapted. The sliding pinion is changed and made in steel.

 In 1971, a variant running at 21,600 vibrations per hour and named Calibre 12 is introduced. It becomes the main product of the calibre family. It uses a stronger barrel spring. The gear train and balance wheel are adapted. The chronograph hammer is modified to improve shock-resistance.


Having a love for complications and complicated watches, makes me love Chronograph watches. At first two register chronograph for simplicity of the dial and providing chronograph functionality for the most. Then the three-register chronograph for the complication of movement and the history of the movements, like of the iconic Omega Ref. 321, Ref. 861 (used in famous moon landing), Zenith El Primero, Venus mostly used in Breitlings, Landeron, and one of the most well-known movement makers Valjoux. With their famous Valjoux 72 put in the vintage Rolex Pre Daytona’s and of course the big dog Patek Philippe reference 2499 using Valjoux 88 my favorite which sold in auction for $3.30 Million in 2018.  I also love the Heuer Caliber 11 first micro automatic chronograph movement with date.

A Chronograph is simply a watch that combines the function of a stopwatch with a timekeeping display watch, by utilizing an independent sweep second hand. Chronographs often have complications on the face of the watch which can be used to record different time measurements, moon cycles, heart rate and more. Chronographs have usually have a separate buttons to stop, start, and reset (unless it is an monopusher) the stopwatch complication, with the start button typically at the two and four o’clock position.

The name Chronograph is derived from the Greek words ‘Chronos’ – the personification of time – and ‘graph’, meaning to write. The first modern Chronograph was created in 1816 by French watchmaker, Louis Moinet. Invented solely for use in union with astrological equipment, Moinet’s Chronograph could measure time accurate to 1/60th of a second – an unrivaled degree of precision at the time of its creation.
