Photonics 4 Masterpieces: Colors

This Conference organized by Swissphotonics, will take place in the framework of the EPHJ International Tradeshow, the most important annual exhibition for Swiss suppliers of watch industry and micro technology.

Color lies at the heart of watchmaking and jewelry—defining aesthetics, perceived quality, and brand identity. Yet achieving precise, reproducible, and innovative colors remains a complex technical challenge, especially as materials, coatings, and manufacturing processes evolve.
Swissphotonics invites you to a dedicated workshop at EPHJ exploring how photonic technologies enable next-generation color solutions for the watch and jewelry industry. The workshop will bring together experts from industry and research to discuss advanced methods for color generation, measurement, and control.
Topics will include structural colors based on nanophotonics, laser-based surface functionalization, thin-film coatings, and high-precision color metrology. Participants will gain insights into how these technologies can enhance durability, sustainability, and design flexibility while ensuring consistency across production.
Designed for engineers, designers, and decision-makers, this workshop offers a unique opportunity to connect photonics innovation with the creative and technical demands of luxury manufacturing.

Join us at EPHJ at PALEXPO, Geneva, on June 18, 2026, to explore how light enables new dimensions of color, to presentations in the morning and a roundtable in the afternoon. No registration is necessary and participation is for free.
