EPHJ, the trade fair for high precision, brings together players from watchmaking and jewellery, microtechnology and medical technology at Palexpo. It runs in Le Grand-Saconnex from Tuesday 8 to Friday 11 June 2027.
The story
EPHJ was founded in 2002 in Lausanne with 92 exhibitors. Its founders are André Colard and Olivier Saenger. Around a quarter of the first exhibitors have taken part ever since.
The fair later moved to Palexpo in Geneva. Its growth rests on principles set from the start. All exhibitors use the same standard stand module. Stand prices remained stable for twenty years.
In September 2021, EPHJ was the first Swiss trade fair to reopen after the health crisis. The 20th edition, in 2022, welcomed around 700 exhibitors from 15 countries. The fair has also opened up to medical technology.
Swiss exhibitors come from 22 cantons. Neuchâtel, Bern, Jura, Geneva and Vaud send the most. French-speaking Switzerland accounts for 64% of Swiss exhibitors.
In June 2025, the European group Easyfairs took over the fair. The founders chose it to continue the event in the same spirit. Alexandre Catton leads the team running the fair.
The 24th edition took place in June 2026. It gathered nearly 800 exhibitors from 18 countries and around 20,000 professional visitors. Travel restrictions linked to the G7 summit in Évian weighed on attendance in the first days.
The 2026 edition hosted the first Global Watchmaking G7, devoted to the future of watchmaking. Federal President Guy Parmelin visited the fair. The Exhibitors’ Grand Prix went to Louis Bélet SA for its PCD drills with internal lubrication.
Who organises it
The fair is organised by Easyfairs, a European trade fair organiser that has owned EPHJ since 2025. Alexandre Catton is its director.
What to find
The fair covers four sectors. These are watchmaking and jewellery, microtechnology, medical technology and critical applications. It is open to trade visitors only.
The organisers expect 20,000 professionals from five continents. In 2026, round tables covered AI in the workshop, additive manufacturing, the space industry, precious metals and training. The 2027 programme has not yet been published.
