The five nominees for the EPHJ Great Exhibitor Award 2021 have been determined

After the deliberations of the 2021 Grand Exhibitor Award jury, which analysed the numerous innovations received, a list of 5 candidates was selected. These 5 innovations have been forwarded to all exhibitors who will vote according to their preference. The winner will be announced on 14 September during the Exhibitor Evening at EPHJ.

The Grand Exhibitor Prize jury, composed of Mr Eric Rosset, Professor HES-SO, Pierre Amstutz, Director of the Geneva School of Watchmaking, André Colard, Founder of EPHJ, Olivier Saenger, Founder of EPHJ and Alexandre Catton, Director of EPHJ, selected the following 5 innovations:


STS offers the watchmaking and jewellery industry a true innovative alternative to rhodium, the world’s most expensive metal.

STS spent one year developing and testing two alternatives to rhodium in the laboratory. Of these two alternatives, platinum is the most efficient. Using platinum, it is possible to produce large quantities of a coating with the same technical specifications and colour as rhodium. This chemical and technological innovation offsets the global surge in the price of rhodium, which is now costs than CHF 800/g!


Panatere’s innovation involves producing solar steel using a solar furnace located near watchmaking production sites.

To comply with environmental requirements, Panatere has developed a sustainable innovation to produce 100% recycled and recyclable 4441 grade (AISI 316L) stainless steel that combines local distribution with the circular economy thanks to its solar furnace. The initial results reveal a significantly smaller carbon footprint during the production of secondary steel, i.e. 165 less than a standard steel.


Amorphous metal alloys boast extraordinary properties that are now coming to light thanks to the Vulkalloys range.

The amorphous metals in the Vulkalloys range, designed and patented by Vulkam, are ideal for micro- mechanisms and offer unique properties: exceptional elasticity and hardness, non-magnetism, resistance to corrosion, wear and scratches, biocompatibility and lightness. These Ni-based Vulkalloys are produced on an innovative production line using a unique three-step process: production of the raw material (amorphous metal slugs), thermomoulded preforms and finishing by laser cutting, electro-erosion or bar turning.


Reebber, a truly innovative recycled rubber developed by Mestel.

While developing and approving a process for devulcanising and grinding rubber, Mestel created Reebber, a new recycled rubber that has the original characteristics of rubber while offering infinite customisation (in terms of both colours and patterns), resistance to torsion and tearing, adhesion to substrates and good chemical resistance.

Positive Coating

Positive Coating leverages innovations to coat watch components in colour gradients.

Thanks to its expertise in PVD and ALD treatments, Positive Coating’s innovation leverages technology enabling colour gradients – such as a rainbow, two-tone or an explosion of colours – so that it can be applied to the complex geometry of watch components. This innovative technology is already being used by some brands.

Each year, companies and professions specialising in watchmaking and jewellery, microtechnologies and medical technologies meet in Geneva for the world’s largest high precision trade show – EPHJ. Find out more about what the trade show can do for you and the services it offers:
