It's a trade fair that brings together players in technology and microtechnology. It's essential to be there, as that’s where your presence on the market is reinforced and new connections established for the future.


Watches and Jewellery

It allows us to meet all our customers and / or suppliers in one week, establish connections on a more personal level, and expand our network by meeting new people who are working in our field.

Very good contact with foreigners, carries a very good message about outsourcing outside Switzerland.



As our Swiss agency has been set up only recently, the trade fair has been a gateway to companies that hadn’t known us before.

An interesting trade fair because we exhibit surrounded by our customers and potential customers, with visitors who all work in the target areas of our operations.

At a time when Industry 4.0 is becoming a thing, business is still driven by people getting together, and the fair will respond to the digital transformation by preserving its character, even if it changes how this character is expressed.

Mimotec SA

Watches and Jewellery

Every year, the EPHJ is the place to be for the watchmaking supplier community, a date not to be-missed in our calendar, as it allows us to meet so many of our customers and counterparts among suppliers.

Ciposa SA

Watches and Jewellery

A very good platform for sharing and meeting in the precision and micro-technology sectors.

Fondation Horlogère 3900 Porrentruy

This show is particularly interesting for us because we invite four apprentice watchmakers from the CEJEF. Through working on our stand, they show everyone their craft, and also find out more about its future by visiting craft stands.

Ceramaret SA

Watches and Jewellery

A very user-friendly show with space of four days for many meetings with customers and suppliers that would certainly take several weeks if we had to visit them. And the show definitely makes it possible to meet new potential customers. BRAVO and THANK YOU! See you next year. Best regards,

Sy&Se Sàrl


For Sy&Se it’s important to tell people about our products, but it’s equally important to speak directly with Swiss economic actors. The number and quality of the companies represented at the EPHJ was impressive, our objectives were fully achieved.

Metalor Technologies SA

Watches and Jewellery

With such a concentration of professionals, it’s essential for us to be present at this show to meet both our customers and our competitors. The atmosphere is always very pleasant. Thank you
