Casio is preparing to expand its Edifice lineup with the EFS-S660 series, and newly surfaced high-resolution images now offer a much clearer view of the design. The renders follow an earlier, lower-quality leak and confirm several details about the solar-powered chronograph ahead of its expected launch.
Refined Dial and Solar Technology
The updated images reveal a subtle honeycomb texture across the main dial surface, paired with a concentric ring pattern on the subdial. Both treatments are functional rather than purely decorative. Because the watch relies on Casio’s Tough Solar charging system, light must reach the photovoltaic cell beneath the dial. The company has reportedly reduced the surface area required for efficient solar charging, which allows for this level of dial detailing without compromising power generation.
Chronograph Layout Explained
The new renders also make the watch’s chronograph layout easier to parse. A lower subdial tracks stopwatch minutes, while the long central hand counts elapsed seconds. The upper subdial handles fractional measurements down to 1/20 of a second, with the stopwatch function capped at a 60-minute measuring window. A tachymeter scale is positioned on the inner ring beneath the sapphire crystal, a placement likely dictated by the limited space on the watch’s octagonal case design.
Materials, Dimensions, and Pricing
Two colorways are confirmed for the initial release. The EFS-S660D-1A features a stainless steel case and a bracelet that echoes the styling of the earlier EFS-S650 model. Alongside it, the EFS-S660PB-1A comes in a gunmetal ion-plated finish paired with a textured rubber strap that uses a tire-tread-style pattern. The case measures a compact 38.3 mm in diameter and includes a sapphire crystal, 100 meters of water resistance, and a low-battery indicator. Pricing is estimated at around $220, with availability still expected in August.
