Model History
Edifice debuted in June 2000 with the EF-100, the line's first watch and Casio's first true analog chronograph with an all-metal case aimed at motorsport enthusiasts. Until that point most of the Casio catalogue revolved around digital or rugged watches: Edifice instead was born to offer a more formal and elegant language, while remaining firmly anchored to the imagery of racing — a wrist chronograph that, as the brand's positioning still states today, should "look fast even standing still".
Over the course of the 2000s the line explicitly strengthened its ties to motorsport, leading to direct collaborations with teams and drivers in the sector — including, more recently, the long-running partnership with Honda Racing, celebrated with several limited-edition models. At the same time Edifice progressively integrated the Casio catalogue's most advanced technologies: Tough Solar charging to do away with battery replacement, radio-signal synchronization for automatic precision, and more recently Bluetooth connectivity with smartphone linking, lap-timing functions on the track (memory for up to 200 laps), and greater resistance to vibration for use in real motorsport environments.
Today Edifice represents Casio's answer for those seeking a chronograph with a sporty character but a more refined aesthetic than the brand's more strictly "instrument" lines, such as Pro Trek or G-Shock: an all-metal case, multi-layer dials inspired by racing-car dashboards, and a range spanning from entry-level quartz models to high-end references with Bluetooth and more refined materials.

Main Executions
Some Edifice limited editions dedicated to Honda Racing reprise the team's historic "Championship White" race-car livery: a detail that sums up the logic of the entire line well, born not as a simple sports watch but as a genuine product derived, in both aesthetics and materials, from the world of racing.
