Design and Craftsmanship

Sophisticated Metal Finishing

The distinctive structural beauty of the metal bezel is achieved through multiple processes. After forging the intricate form, the top surface is pressed with a finely uneven texture, and openings are cut into the lugs. This industrial aesthetic is finished with a hairline polish on the sides to enhance the texture of the metal while tempering its shine.

Functional Aesthetics

The pairing of a metal bezel with a textured bio-based resin band evokes a "combination of materials" theme central to modern industrial design. The square dot pattern on the band echoes the bezel’s texture, providing a superb fit that complements both casual attire and professional gear.
