BREITLING CHRONO-MATIC NAVITIMER “PIZZA” REF. 1806
- Technical datas
Founded in 1884 by Leon Breitling in St Imier, in the Bernese Jura, Breitling is well known for designing and watchmaking chronographs for aviators.
The brand contributes to a part of the watchmaking history by developing reliable, robust and high-performance instruments.
In 1915, Breitling invents the 1st independent chronograph pusher. In 1923, an evolution permits to separate the « on/off » and « reset » functions. Then, in 1934, the brand achieved this chronograph movement by developing a second independent push-button for resetting to zero.
Breitling launches the Navitimer model in 1952 for the world of aeronautic.
In 1969, Breitling participates to develop the first self-winding chronograph movement, in association with independent companies like Heuer, Buren and Dubois-Depraz.
Breitling called it Chrono-Matic, while Heuer used the name Calibre 11.
The presented model is a Navitimer, ref. 1806.
It is called « pizza » because of its oversized stainless steel round case of 48 mm diameter.
The case back is screwed and the crown is at 9* (special feature of the Chrono-Matic movement). It has also a rotating bezel with slide rule, a black dial with 2 registers and date display at 6. The movement is self-winding with micro-rotor, the Chrono-Matic.
* the crown is located at 9 because watchmakers were told by both aviators and drivers, that the crown hindered them in handling the pushers when the crown is at 3. It is the reason why watchmakers moved the crown at 9.
