About Tube Case Sapphire

An all-sapphire watch case has received attention from the distinguished and sophisticated Swiss watch manufacturers as a fashionable skeleton jewel piece. The watch is made from Namiki's patented tube case sapphire, includes a band also made from pink sapphire, and builds on Namiki's precision processing technology.

The tube case sapphire, in which the sapphire watch window and back cover are integrated seamlessly, is ultra-finely polished inside and sealed on both sides with colored sapphire rods as shown in the photo. this is an example of the unique capabilities of Adamant Namiki, thanks to our core technologies and EFG methods. The design is an example and can be tailored to the customer desires.
