The full sapphire case is made from plates of sapphire that are first cut from the solid sapphire and then milled and polished down to the correct shape. Limited to 100 pieces. Pay attention to avoid collisions and avoid materials of the higher or the same hardness, such as diamond rings, watches, glass knives, etc.

It is difficult to make the sapphire case for sapphire crystal is too hard but it is also easy to crack. To adopt ultrasonic polishing and CNC cutting technology, and use diamond drill bits to drill at a speed of 10,000 revolutions per minute to cut the sapphire.

The texture of sapphire is different from glass, resin, and plastic. Perspective the movement through the crystal clear case, make you experience the technology more impressed.

To overcome gravity. The original escapement mechanism is fixed, and the escapement mechanism of the tourbillon rotates 360 degrees continuously, which will integrate the azimuth errors of the parts, offset each other, and correct the errors caused by gravity on the clock and watch parts.
