H2i – Accuracy Motion winner of the 2020 Grand Prix des Exposants

Although the 2020 edition of the EPHJ Trade Show was cancelled due to the pandemic, the traditional Grand Prix des Exposants was able to go ahead as normal as a result of the many innovations received by the Jury for initial selection. The exhibitors’ votes then rewarded the remarkable innovation of the Neuchâtel company H2i for its contribution to high-precision watchmaking.

From the many applications received for the 2020 event, five innovations were selected by the members of the EPHJ Grand Prix des Exposants Jury, which included Pierre Amstutz, director of the Geneva watchmaking school, Prof. Dr Eric Rosset of the HES-SO and Alexandre Catton, Director of the EPHJ Trade Show. Those selected were Fischer Connectors SA, Norimat, Meyrat SA, Tornos SA and H2i. Exhibitors then went on to vote for the winner among the five finalists.

After the vote between professionals of high-precision, it was the Accuracy Motion of the Neuchâtel-based company H2i that came out on top: a well-deserved success rewarding real technological progress in testing and adjusting the chronometric precision of mechanical watch movements.

“We are very happy with this recognition from our peers”, celebrated Jean-Charles Rousset and Emmanuel Baudet, co-directors of H2i. “We have worked tirelessly with the Acrotec Group R&D team at our shared premises in Cortaillod to push the technological limits of acoustic measurement for watches. This product enables manufacturers to put in place test and control measurements with optimal chronometric quality for their timepieces before marketing.”

The Grand Prix des Exposants Jury highlighted that the Accuracy Motion revolutionises testing and adjusting for the chronometric precision of mechanical movements in 32,400 watch positions in space, whereas the limit previously was just 6 positions. Through direct adjustment with an inertial and strain wave gearing unit, the product is closer to aerospace technologies than to standard industry.
