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.

Crown Operations

Some water-resistant models (10BAR, 20BAR) have a screw-in crown. When you need to perform a crown operation, rotate it towards you to unscrew it. Then pull the crown out. Avoid applying undue force when pulling.

Stopwatch

The stopwatch measures elapsed time up to 11 hours, 59 minutes, 59.95 seconds.
Important!
– Do not operate the stopwatch with the crown pulled out.

To measure elapsed time

  1. Press (A) to start the stopwatch
  2. Press (A) to stop the stopwatch
  3. Check the elapsed time.

Feedback from Users *accumulated information from our own comments and emails, forum threads, socials, reviews, etc.

PROs
+ the movable ring is protected under a fixed crystal, even though that means turning it with a rather small knob
+ a great looking and functioning watch to wear while you do everything
+ very Good build and finish quality
+ a budget price
+ very accurate

CONs
– the hands on the stopwatch function tends to creep out by about 5 seconds if you leave it running overnight
– the bezel moving crown makes the job of using the slide-rule a bit cumbersome
– the numbers on the E6B slide rule around the bezel are small
