We are a manufacturer of custom sapphire products. Our professional factory has many years of dedicated experience in processing high-quality sapphire watch cases. We work closely with global watch brands to create unique, scratch-proof masterpieces.
The Magic of Doped Sapphire

Creating vibrant colored sapphire is like alchemy. During the crystal growth process, we add specific trace elements. These are known as “dopants.” This precise process changes the crystal’s structure at a molecular level.
This creates stable, stunning colors through the entire block of material. Our advanced growth techniques ensure the color is perfectly even. You will not see streaks or weak spots in the final polished case.
A Spectrum of Possibility

We offer a spectacular range of custom colors for your luxury timepieces. The main choices include:
- Blue Sapphire Watch Cases: Deep, classic ocean tones.
- Red Sapphire Watch Cases: Bold, energetic, and eye-catching.
- Yellow Sapphire Watch Cases: Bright, luxurious, and unique.
We can also customize other shades to meet your brand’s specific aesthetic vision.
A Smart Alternative to Green Sapphire

Please note that green sapphire is currently unavailable for commercial sale due to temporary policy restrictions in the global raw material market. We strictly comply with international manufacturing regulations.
However, we have a perfect, commercially available solution for that coveted green aesthetic. We proudly offer premium Green Nanosital as a stunning alternative. Our [Green Nanosital Watch Cases] deliver the exact vibrant color, exceptional optical clarity, and structural resilience you need, allowing you to bypass regulatory hurdles without compromising on luxury.
Precision Manufacturing You Can Trust
Working with colored sapphire requires extreme expertise. Machining colored sapphire is often more difficult than machining transparent material. Changes in color density can affect how the material reacts to cutting tools.
Our factory utilizes state-of-the-art 5-axis CNC machines. We ensure that every angle and complex curve is perfect. We provide hundreds of hours of flawless diamond-paste polishing. The result is a vibrant, smooth, and highly durable housing for your high-end movement.
