22STUDIO’s 4D Concrete Watch brings architecture to life on your wrist, displaying time’s passage through an exquisitely crafted space. The passing of the three-dimensional watch hands across the cured-concrete dial creates a unique play of light and shadow, while the movement’s echo in the darkness below the spiral stairs serves as a constant reminder of the 4th dimension: time.  
 
4D Concrete Watch Automatic : Signature Steel
 
The dial on the Signature edition naturally features our unique spiral staircase, but adds a high-detail scale. The bezel top is shaped at a precision angle and polished to a mirror finish. The date atrium, shaped and polished in the same way as the bezel top, allows you to see the date clearly.
