In 1977, French-speaking Switzerland had no independent analysis centre in the fields of electroplating and metallography. Henri Dubois, realising the need among local companies for expertise in these two fields, took the decision to open his own laboratory, with a workforce of 3.
1985 was the big turning point for watchmaking. The Swiss Watchmaking Federation separated from CCF (the Reliability Test Centre). Realising how complementary this company was to his own, Henri Dubois did not hesitate to take it over. Thus the firm became "Laboratoire Dubois CCF SA". Now the laboratory could offer the best watch operating performance tests, as well as a wide range of other tests.
The watchmaking part was further strengthened in 1992 with the takeover of CTM (watch technical testing), a State company which was closing. This development led to the concentration of typically watch-related activities within a new company, "Chronofiable SA", founded in 1993. "Laboratoire Dubois SA" was structured under three activities: materials testing, technical assistance, chemistry and environment. A new activity would subsequently be added to round off this range of services: tribology.
Thereafter, in order to further develop its skills, in February 1995 Laboratoire Dubois became the first test laboratory in Switzerland accredited under standard ISO17025 for metallography, materials testing and inspection.
In 2003, Chronofiable SA was incorporated into the legal entity Laboratoire Dubois SA.
In 2011, a monitoring activity, technical-legal assistance, expanded the company's services in the form of a monthly bulletin available by subscription.
In 2014, Henri Dubois won the Gaia Award in the "Enterprise" category. This award crowned nearly 40 years of continuous commitment to serving the industry. In the same year, the laboratory received accreditation for its indirect watch shock tests.
Today, with a workforce of nearly 35, Laboratoire Dubois is an essential partner for numerous industrial sectors, while maintaining and developing particularly advanced skills in the watchmaking sector.
