The Casio Edifice EFR-S108DE-2WC is a solar-powered men's dress watch from Casio's premium Edifice collection. It features a striking blue sunray dial housed in a slim stainless steel case, offering a refined aesthetic suited for both professional and casual wear. The watch draws power from Casio's Tough Solar technology, which charges the battery via any light source, eliminating the need for battery replacement under normal use conditions.

This model connects wirelessly to smartphones via Bluetooth using Casio's Mobile Link system, allowing automatic time synchronization and one-touch time adjustment through the dedicated smartphone app. The case offers 100-meter water resistance, making it suitable for swimming and everyday water exposure. Additional features include world time coverage across 38 cities, a 1/100-second stopwatch with 24-hour measuring capacity, a countdown timer, five daily alarms, and an auto-calendar accurate through 2099. The mineral crystal display is protected by a hardened sapphire-coated face, and the watch includes a stainless steel bracelet with a fold-over clasp.
