Breitling Chrono-Matic 2112: the birth of the automatic chronograph in 1969
· Mamontrevintage
On 3 March 1969, several manufacturers announced an automatic chronograph developed jointly. This technological breakthrough transformed watchmaking: an automatic movement could now power a true chronograph. At Breitling, the innovation took shape in the Chrono-Matic, recognisable by the crown positioned on the left of its case.
Breitling: a timekeeping tradition since 1884
Léon Breitling founded his company in 1884 in Saint-Imier, before Breitling expanded its production in La Chaux-de-Fonds. The business specialised in chronographs, counters and timing instruments, particularly wherever a quick reading of elapsed time was useful.
Under subsequent generations, Breitling helped refine chronograph pushers. Independent start and reset controls, followed by the separation of functions across different pushers, contributed to increasingly practical instruments for measuring short time intervals.
The Navitimer, introduced in 1952, illustrates Breitling's connection with aviation. Its peripheral slide rule supports navigation and conversion calculations. This tradition of instrument chronographs prepared the way for a more difficult advance: combining automatic winding and a chronograph in the same movement.
1966–1969: the Chronomatic project, known as “Project 99”
By the mid-1960s, customers wanted both automatic watches and sports chronographs. Combining them remained technically challenging, because the chronograph mechanism occupied considerable space while the automatic rotor needed enough room and an effective transmission.
The Project 99 brought together several specialisms: Breitling and Heuer-Leonidas contributed their chronograph expertise, Hamilton-Büren provided knowledge of automatic micro-rotors, while Dubois Dépraz developed a dedicated chronograph module. Rather than merely stacking existing components, the consortium designed a coherent industrial architecture.
The movement was presented on 3 March 1969 at simultaneous press conferences in Geneva and New York. That date is a milestone in the automatic-chronograph race, which also saw major developments from Zenith and Seiko in the same year.
Calibre 11: micro-rotor and chronograph module
The calibre 11 combines an automatic movement from Büren with a chronograph module developed by Dubois Dépraz. This arrangement shows how a modular design can unite automatic timekeeping driven by an oscillating weight with pusher-operated chronograph functions.
The crown sits on the left side of the case, while the chronograph pushers remain on the right. This position reflects the movement's construction and became a visual signature of early Chrono-Matic watches. It also supported a marketing message at the time: an automatic watch need not be wound daily through its crown.
The usual calibre 11 layout includes two registers, chronograph indications and a date window. Later family members included calibre 12 and variants such as 15. These must not be treated as one universal specification: Breitling offered its Chrono-Matic across several references.
Breitling 2112: the design of a transitional chronograph
Reference 2112 belongs to the early Chrono-Matic era and has the silhouette of a late-1960s sports chronograph. Its steel case and two-register dial reveal a transition: the watches retained proportions inherited from earlier years, but their movements were now designed for automatic winding.
Specialist archives document variations in the movements and dials used for this reference. The Breitling 2112 illustrated here is associated with calibre 11. Chrono-Matic therefore refers to a wider technical family, not a single dial design or calibre number.
The pusher layout, opposite-side crown and dial-scale details capture the changing era. The automatic chronograph preserves the familiar operation of a hand-wound chronograph while freeing daily timekeeping from manual winding.
A collective invention in mechanical-watch history
The year 1969 saw exceptionally productive competition. Zenith presented an integrated high-frequency automatic chronograph, Seiko developed its own automatic solution, while the Chronomatic group favoured modular construction combining the expertise of several firms.
The Breitling Chrono-Matic embodies the latter approach. Its case, calibre and unusual crown location illustrate how sports chronographs changed on the eve of the 1970s, heralding a new generation of automatic mechanical watches.
