Fresh high-res renders of Casio's EFS-S660 chronograph reveal a honeycomb-textured solar dial, a 1/20-second stopwatch layout, and confirm two colorways ahead of an expected August release at around $220.

We just covered the unofficial reveal of the Casio Edifice EFS-S660 watches two days back. At the time, we had low-res renders of the watch (via G-Shock Hai Phong). Since then, high-res renders of the same watches have now shown up via Casioblog.

Going by the new set of images, the dial has a mild honeycomb texture across its surface and a ringed pattern on the subdial. They're both functional instead of decorative, since Tough Solar watches need light to reach the cell beneath the dial to generate power. Casio has reportedly gotten better at shrinking the surface area solar charging actually needs — this explains why the design can afford this level of surface detail without really sacrificing charging performance.

The layout also becomes easier to analyze: the lower subdial tracks stopwatch minutes, the long central hand counts seconds, and the top subdial handles fractions down to 1/20 of a second, capped at a 60-minute measuring window.

The tachymeter scale sits on the inner ring beneath the crystal rather than on the bezel itself, most likely due to limited space on the case's octagonal design. Two colorways are confirmed for launch: the steel-cased EFS-S660D-1A with a bracelet resembling the earlier EFS-S650, and the gunmetal ion-plated EFS-S660PB-1A on a rubber strap with a tire-tread-style texture.

Case width is confirmed at a compact 38.3 mm, with sapphire crystal, 100 m water resistance, and a low-battery indicator. Pricing is estimated around $220, with an August release still expected.
