Lab Created Sapphire & Ruby Watch

Thanks to the developed Czochralski crystal-grown method, we can produce high purity, large-size, flawless rough sapphire, and ruby crystals to make these unique watches.

The cases cost about 1000h of production, and all the components, holes, and curve edges are machined precisely. They are not only watches but also artworks.

The colors could be red, blue, pink, green, aqua, purple, yellow, orange, paraiba, and colorless.
