At the age of 50 and after more than 25 years of experience in the field of cutting tools, Patrick Parrenin wrote a new page in his career by creating with his son the Sarl Complexcoup in Damprichard in a 40 m² prefabricated block.

Very quickly recognized by large watchmaking and medical groups, the company is too quickly cramped and has to move to premises slightly larger in order to accommodate new machines and thus meet the demand.
The launch of a new construction is carried out in parallel, still in the same village.


Moving to the current premises. Investment in new state-of-the-art machines, suction system, last generation watering system.
The team is now flourishing in the manufacture of increasingly complex parts.

Retirement of its creator and takeover of his son, Gael Parrenin.
The company now has 5 employees and continues to advance on the principles of its founder: rigeur, precision, responsiveness, development and curiosity.
