How it wears, by wrist size
Superb — 7.8mm slides under any cuff and the ~40mm case reads classic.
Ideal; arguably the best-wearing sub-$200 Casio ever made.
Slim and refined; size up to the standard Edifice chrono if you want bulk.
Wears dressy-small, which is the design intent.
Buy or skip?
Editorial take: 8.5/10 — the sub-$200 dress watch to beat.
The EFR-S108D is Casio quietly embarrassing the fashion-watch industry: sapphire crystal, 7.8mm thin, 100m water resistance, and an octagonal bezel that gives it genuine design identity — for $110–$170. Nothing from a mall fashion brand comes close on specs, and the slim case wears better than watches five times the price. The only honest knocks: the quartz is basic (no solar here), and the integrated-look bracelet is fiddly to size.
- You want solar or Bluetooth — this is plain quartz (the EQB line has the tech, at 10mm+).
- You want a mechanical movement — look at the Orient Bambino instead.
- You dislike integrated-style bracelets — strap options are limited.

| Bracelet | Sizing requires a pin tool; a $5 kit or any jeweler handles it. |

| Resale | Modest but real — the popular colorways hold value unusually well for a Casio. |
Frequently asked questions
Is the Casio Edifice EFR-S108D sapphire?
Yes — a genuine sapphire crystal, which is the headline spec. It is the cheapest sapphire-equipped steel sports-dress watch from a major brand.
Is the EFR-S108D automatic?
No — it is a three-hand quartz, which is exactly how Casio got it to 7.8mm. If you want automatic in this style, the Citizen Tsuyosa is the answer.
EFR-S108D vs Tissot PRX?
The PRX is the Swiss original with better finishing at $300–$400; the Edifice gives you the silhouette, sapphire and 100m for half the money. Different budgets, same taste.
Which EFR-S108D color is best?
Black (-1AV) is the versatile pick; green (-3AV) and turquoise (-2BV) are the lookers and sell at the top of the price range. All share identical specs.
