Covering the fantastic RMUL2 manual winding movement with stunning transparent Sapphire case, and brightened by 18k rose gold inner ring, AET Sapphire watch not only perfectly show s the charm of Sapphire with transparent texture, but also manifests a epoch-making artistic beauty.

AET chooses quality clear and permanently shining Sapphires to wirecut. Dozens of procedures, thosands of hours' machining time - above the industry standard, only to create the brightest Sapphire cases. 30% success rate makes it more precious.

Normal cases need one whole curved surface, but to make the Sapphire cases need three stitching curved surfaces: the upper case, bridge, and the bottom case, which rises higher machinig skills.

The size of hole sites on AET Sapphire watch vary from one to another, taking 200 times accurate drilling for 10 days. The Sapphire and screws are separated by unique metal gaskets, so they can share the forces against cracking. It will take almost 7 hours to scrwe, even for the most skilled artisans, to maintain the case's balance.

Distinguished three-layer case's water resistence is up to 50m. Each hole is covered by a matched waterproof material, connected by another waterproof layer, and sealed with two pure and transparent wterproof rings.
