Casio Edifice EFRS108DE-2AV Slim Light Blue Textured Bracelet

Casio Edifice EFRS108DE-2AV: Slim Without Compromise

The Edifice Slim series proves Casio can do refined. At 7.8mm thick, the EFRS108DE-2AV sits flatter on the wrist than most quartz watches at any price. The flat octagonal bezel gives it an angular, modern look that sets it apart from the usual round dress watch, and the light blue textured dial is more interesting in person than the spec sheet suggests.

The Dial

Light blue with a textured surface that adds dimension to what could otherwise be a flat quartz dial. Applied polished steel markers catch light cleanly, and the steel-tone hands have luminous fill for low-light reading. It’s a three-hand date configuration — no chronograph pushers, no subdials, just clean timekeeping. The date window sits at 3 o’clock.

Build Quality

The 39.9mm case is solid stainless steel with a screw-down caseback. At 110 grams with the bracelet, it has enough heft to feel substantial without being heavy. The mineral crystal protects the dial — not sapphire, despite the slim profile. The tri-fold sport clasp on the bracelet is secure and easy to operate. Water resistance is 100 meters, which is generous for a watch this thin.

Why 7.8mm Matters

Most watches in this price range are 10-12mm thick. The Edifice Slim at 7.8mm slides under a dress shirt cuff effortlessly and wears more like a piece of jewelry than a tool. Casio achieved this without sacrificing water resistance or build quality, which is the real engineering story here.

The Bottom Line

The EFRS108DE-2AV is for anyone who wants a slim, well-built quartz watch with a dial color that stands out from the usual black, blue, and white options. The light blue textured dial and octagonal bezel give it personality, and the slim profile makes it one of the most comfortable watches you can buy under $200.
