Casio Edifice EFR-303 series: 316L steel case, diamond-like coated anti-scratch crystal, running-seconds chronograph quartz movement, and luminous hands.
The Casio Edifice EFR-303 brings the sharp, sport-formal crossover style that defines the Edifice line. Inside sits a multi-function imported quartz movement with a dedicated running-seconds sub-dial -- great for timing intervals with precision. The case is constructed from top-grade 316L stainless steel for lasting corrosion resistance, while the crystal receives a premium diamond-like carbon (DLC) anti-scratch coating for exceptional clarity and toughness. A 316L steel bracelet completes the build, and the watch carries meaningful water resistance for everyday situations. Luminous hands and markers ensure legibility in low-light conditions, and full manufacturer-style packaging is included.
Yes, the 60-second, 60-minute, and 12-hour sub-dials all register accurately when the pushers are operated. The reset snaps back to zero cleanly.
The case is approximately 43mm in diameter with a thickness around 12mm, which is a solid sport-watch size that wears well on average to larger wrists.
Yes, the bezel markings are engraved and filled, not just printed, so they remain readable even in bright conditions.
