Casio has discovered a whole treasure trove in its “oak” design. After seeing these forms in G-Shock, Collection, Sheen, Edifice, and even in wall clocks, it now returns to the charge with new Edifice models featuring octagonal bezel and multi dials. It is certainly not the first time it has done it. You will remember those EQB-1100 and EFS-S570 that also carried it. Based on those models, we now see similar EFB-680 Series in a bezel that comes engraved and a sapphire crystal. The rest of the module is straightforward. It is typical with three-year battery life, date, and one-hour chronograph.
