The Hölstein watch manufacturer has long worked in partnership with research and engineering institutes. It recently presented a new timepiece featuring an avant-garde dial whose titanium surface has been treated with laser technology that divides light into its different components, creating a rainbow effect, depending on the angle of observation.
Without the addition of a single pigment, the dial changes colour from blue to green and purple, like the colouring of iridescent beetles. This laser treatment creates a phenomenon called optical interference, which destroys red light waves, while green and blue ones are reflected.
Everything on the dial – the logo, hour-markers, minutes track and text – has also been produced using laser technology, but using a different process resulting in a 3D effect creating the illusion that these elements have been applied in the traditional way. The laser technique used for this dial is a first in Swiss watchmaking. It was developed in partnership with a research laboratory affiliated to the Swiss Federal Institute of Technology in Zurich.
The dial of the new ProPilot X Calibre 400 Laser is housed in a 39mm titanium multi-part case, as are the bezel, the crown and its safety protection, as well as the three-link bracelet. Water-resistant to 100m, this timepiece is equipped with the Oris Calibre 400 self-winding mechanical movement, providing high antimagnetic resistance and ensuring rating accuracy of plus or minus three to five seconds per day, which corresponds to COSC standards, along with a 120-hour power reserve.
