Eberhard & Co., La Chaux-de-Fonds, Swiss, "Extra-fort", Case No. 1629-439 26, 39 mm, circa 1950
A rare, vintage single-button chronograph with 30-minute and 12-hour counter, tachy scale and rare chronograph function with start/stop operated with just one pusher
Case: 18k gold, push back. Dial: silvered.
The company Eberhard was established in La Chaux-de-Fonds by Georges Emile Eberhard in 1887 and specialized in the development of highly accurate chronographs. In the late 1940s, the company launched the Extra-Fort model, which would soon become one of the most important timepieces of the brand. It takes its name from its extremely robust case and is regarded as a forerunner of all Eberhard chronographs.
Even though this timepiece has two rectangular pushers, it is only the pusher in the top position at 2 o’clock that is used for starting and stopping the chronograph. The other pusher does not do anything. Still, this rare variant of a "single pusher" chronograph sits in a beautiful 18K yellow gold case in a modern, comfortable size and the dial has achieved a charming patina over the years, which makes this timepiece a very desirable vintage classic.
