Speed & Intelligence. Technologies continue to advance, with EDIFICE leading the way. This multi-function chronograph from CASIO is actively forwarding the evolution of electronic technologies. EDIFICE combines a fusion of dynamic forms with elaborate face designs, and provides leading-edge, accompanied by uniquely original expressions produced by the movements of various hands. These features are transporting the chronograph into new realms, and unlocking the hidden possibilities they contain. EDIFICE, the watch that recognises the value of speed and time, for people who live in the moment!

EDIFICE Design. Bold, fascinating forms and fine details, combined with simple styling that brings out the essence of metal, give birth to products with clearly designed identities.

Drawing and modeling. A prototype is produced based on a sketch using CAD and a 3D printer. A bold design concept takes shape.

Bold index. An edgy, striking large index is laid out on the dial. Robust modeling with straight lines and basic tones evokes a strong presence.

Forged stainless-steel case. After forging and heat treatment of the stainless-steel material, precision machining is conducted to complete the boldly designed case form.

Polished finishing. Polish finishing by the hands of skilled craftsmen produces beautiful mirror surfaces on the forge-cast stainless-steel case.
