The "TO" series well reflects Tokujin Yoshioka's unique approach to design.

The watches are characterized by an appearance of solidity, making a strong statement with their substantial, sculpture-like designs. While continuing the concept on a watch appearing to have been carved from a single piece of metal, the design has been further refined. Watches with rugged, mechanical, and self-winding movements are now available.
