At Minnexon, we specialize in high-precision CNC machining of sapphire & garnet components such as watch cases and colored sapphire crystals, supplying elite watchmakers across Switzerland, France, and beyond.
From limited-edition prototypes to full-scale OEM sapphire & garnet component production, we deliver unmatched surface quality, geometric precision, and color customization—trusted by the world’s most demanding haute horlogerie brands.
We combine 5-axis CNC milling, ultrasonic machining, and laser-assisted finishing to produce sapphire parts with:
±0.005 mm dimensional tolerance
Optical-grade clarity (Ra < 0.02 µm)
Stress-relieved and bubble-free structures
Crack-free cutting with minimal chipping
Full compatibility with skeletonized or complex watch geometries
Whether your design calls for transparent, black, or curved sapphire cases, we maintain exacting uniformity throughout production.
We serve OEM/ODM clients in Switzerland, France, Germany, and other European watchmaking hubs, offering scalable solutions for both independent brands and established manufacturers.
Colored sapphire is fast becoming the signature of modern haute horlogerie. Minnexon offers fully customized colored sapphire components, including:
Pink, blue, yellow, green, orange, black and hybrid hues
Chromium, titanium, nickel, or iron-doped synthetic sapphire
Excellent light transmission, double refraction resistance
Color consistency across multi-unit production
Each crystal undergoes high-temperature annealing and anti-stress polishing for long-term durability and aesthetic brilliance.

Complete sapphire/garnet watch cases (front, middle, back)
Transparent and colored sapphire dials & bezels
