On the occasion of Watches and Wonders Geneva 2024, ECAL is teaming up with Alloyed to present a collection of watch straps using 3D printing technology.

On the occasion of Watches and Wonders Geneva 2024, ECAL joins forces with Alloyed, a company with expertise in metal printing technologies, to present an original collection of watch straps. Designed by students in the Master of Advanced Studies in Design for Luxury and Craftsmanship program, these bracelets have been developed using 3D modeling programs, enabling the creation of unique pieces that go beyond the limits of traditional techniques.

Five of the 15 concepts devised by the students were selected and 3D printed from a fine powder of TI6AI4V titanium–an alloy composed of titanium, aluminum and vanadium–whose melting point of around 1,600° Celsius is achieved using a laser beam. Regularly used in the aerospace industry, this printing technique, known as Laser Powder Bed Fusion (L-PBF), creates objects with ultra-high-performance mechanical properties.

Each project, presented in the form of a prototype or animation, finds its inspiration in the beauty of nature, through organic structures, as much as in complex systems, closer to engineering. This collaboration brings together technology, craftsmanship and design–in line with the world of haute horlogerie–by combining the expertise of engineers specializing in materials science with the know-how of jewelry craftsmen.
