In horology, the date disc is the rotating component that displays the date through an aperture on the watch dial, a subtle yet essential element that combines functionality, legibility, and aesthetic harmony. Traditionally made of metal, the date disc can now be reimagined in glass, offering a new level of visual purity and design freedom for contemporary watchmakers.
FEMTOPRINT’s glass date discs redefine clarity and refinement in time display. Crafted with micrometric precision, these components allow for exceptional readability and seamless integration into a wide variety of dial architectures. Their inherent transparency enables creative layering, discreet visibility, and a lighter visual footprint, ideal for brands seeking innovative aesthetic solutions without compromising on functionality.
Using fused silica or borosilicate glass BF33, our date discs combine optical excellence with high stability against environmental influences such as UV exposure, humidity, and temperature fluctuations. Precision engraving ensures that numerals remain crisp, legible, and durable over time. Transparent or tinted variants can be produced to complement specific design codes or to achieve distinctive visual contrasts within the dial.
Additionally, the ultra-lightweight design offers tangible performance benefits: fused silica is approximately 2× lighter than sapphire and 4× lighter than brass. By reducing the weight of moving components, the movement requires less energy to operate, resulting in extended power reserve and improved overall efficiency of the watch.
Through these capabilities, FEMTOPRINT offers unmatched creative freedom and dimensional accuracy, enabling luxury watchmakers to explore new aesthetic and functional possibilities while maintaining the precision standards expected in high-end horology.
FEMTOPRINT stands out through its proprietary monolithic microfabrication process, enabling the creation of customized watch dials with integrated apertures, precision-engineered gear teeth, micro-bezels, and high-resolution indices—all structured in a single piece of glass.
