Roger Cornet is a perfect self made man: contractor, inventor and watchmaker. Not contend with a business career rewarded by many successes, this enthusiastic inventor sets on to achieve a world first in watchmaking at the age of eighty-seven.

1929

Roger Cornet chooses a field of extraordinary importance for medical progress and starts a career in radiological devices ands precision mechanics.

1946

The war over, Roger Cornet takes stock of the situation, assesses what is at stake and succeeds in reconciling what he loves doing with what he ought to be doing for his country. He hence sets up his own company under the name Le Prototype Mécanique, which specializes in high precision micro mechanisms. Le Prototype Mécanique is a real success through collaborations with famous aircraft manufacturers such as Dassault and Matra. The company contributes to space programs through micro-electromechanical and space horology developments for the Aerospatiale. It is also involved with leading French laboratories such as the ONERA, the CNRS and petroleum Research.

1965

Le Prototype Mécanique develops an altitude calculator for the Diamant missile. The device is able to calculate 3 850 paths. This is a major achievement, for which Roger Cornet will be congratulated by the General de Gaulle. Roger Cornet contributes to several projects for the Mirage jet planes. He develops shock recorders for the SNCF, the early black boxes. His company prospers, employing 180 people at l'Etang La Ville, over 3000 square meters.

1987

Le Prototype Mécanique is sold. Roger Cornet leaves the company to his managerial staff, and devotes himself to his other passions. His love for automotive engineering led him to collect cars. His enthusiasm for the conquest of the skies is credited by over 1 200 flying hours, including aerobatics.
Admiring masterpiece clocks bearing the names Berthoud, Janvier and Lépine, Roger Cornet decides to start two table clocks from scratch, so that his granddaughters Frédérique and Sandrine may have something reminding them of their grandfather. For some ten years, he develops the timepieces in which the in-line escapement is visible on the dial, and calls upon the manufactury of Sèvres for the decoration. The alignment mechanism, due to become Roger Cornet's trademark, was born.
  

1993

The two masterpieces made by Roger Cornet appear and are admired by experts throughout the world. The making of clocks comprising no less than 250 parts is undertaken, and enthusiastic purchasers are found all over the world.
Encouraged by the response to his fine workmanship, Roger cornet and his son Bernard decide to miniaturize the in-line escapement found in their clocks and to implement it in a wrist watch.
  

1997

Together with his son Bernard, the project manager, Roger Cornet goes for Swiss quality and decide to produce an entirely new Swiss Made caliber. They meet François-Paul Journe, a great specialist in fine watchmaking, who brings the concept to life in his workshop in the purest French tradition of watchmaking, with the quality of a top-of-the-range product.
  
Follows the world first at the Basel Fair in April: presentation of the very first watch with visible escapement above the dial, the Versailles (reference R.C. 640.)
Then comes the Trianon (reference R.C. 841), combining Roger Cornet's French inventiveness with the microtechnical expertise and the making mastery of the Swiss Frédéric Piguet
