EF-554SP

TOKYO, October 5, 2010 — Casio Computer Co., Ltd., announced today the release of a new chronograph model in its EDIFICE line of metal watches—the EF-554SP—featuring a carbon fiber watchface with four inset dials arranged in a three-dimensional layout.

Capturing the essence of speed and intelligence, EDIFICE metal watches evoke a sense of velocity and motor sports energy with the movement of the hands and distinctive face of the watch. EDIFICE watches are especially popular with young people, thanks to their rich stopwatch functions and standout face designs.

The EF-554SP exudes a bold, stand-out image, with a double-layer metal plate attached to the carbon fiber watchface with screws. The face is arranged with four inset dials in a highly unique three-dimensional design.

This dynamic design of the multi-handed watchface enables stopwatch measurements using the movements of the various hands. The small hand at the 6 o’clock position can move back and forth to measure 1/20ths of a second as a retrograde stopwatch, and the stopwatch-hand in the center of the watch face counts seconds. The small hand at the 12 o’clock position counts minutes, and the small hand at the 9 o’clock position counts hours. To enable calculation of average velocity using the stopwatch measurements, tachymeter values are displayed on the bezel.

For the regular display of time, the center hands indicate hours and minutes, the small hand at the 6 o’clock position can also indicate seconds, and the small hand at the 3 o’clock position displays hours in 24-hour format.

Along with the EF-554SP, Casio is also releasing the EF-554D, which offers the same functions and specifications as the EF-554SP but with a grid-style design on a standard-material watchface.

Casio continues to showcase the superior technology and dynamic designs of its EDIFICE line of watches to the world by conducting promotional activities as an official partner of the Red Bull Racing F1™ team.
