In mechanical watchmaking, wheels and gears are fundamental components of the movement’s gear train, transmitting energy from the mainspring to the escapement and regulating torque throughout the mechanism. Each wheel must operate with precise alignment and minimal friction to ensure accurate timekeeping, smooth motion, and reliable power distribution. The geometry, weight, and material of these wheels directly influence movement efficiency and overall performance.
FEMTOPRINT is redefining watch wheel engineering with glass components that combine ultra-lightweight design with unmatched precision. Our microfabricated wheels, crafted from fused silica using advanced laser micromachining, offer a high-performance alternative to traditional materials such as brass.
The Advantage of Fused Silica
Fused silica is exceptionally light — approximately twice as light as sapphire and four times lighter than brass. This reduction in mass allows movements to operate with less energy demand, indirectly supporting extended power reserve potential. Its inherent structural stability ensures wheels maintain their shape and alignment under normal mechanical conditions, making them suitable for the most demanding watch movements.
Precision Engineering and Design Freedom
FEMTOPRINT glass wheels meet the highest standards of Swiss horology, combining technical excellence with aesthetic versatility. They feature ultra-precise geometry for optimal gear alignment, minimal mass to reduce energy load on the movement, and structural integrity to resist deformation under mechanical stress. Beyond function, these components can incorporate micro-engraved markings, optical textures, and surface finishes to enhance visual depth, contrast, and readability.
