Casio Radio Controlled LCW-M100DSE-2AER

About the Watch

The dark blue dial divides the information between three central hands and a compact digital window at six o'clock. Silver-colored indices, clear Arabic numerals, and a bright minute track give the round front a sharp, instrument-like structure. The combination of analog overview and digital information is suitable for a functional everyday watch where multiple time data can be accommodated without the main display losing its clarity.

Materials & Fit

The round case is 40 mm wide, measures 43.8 mm from lug to lug, and has a thickness of 9.4 mm. The case and bezel are made of stainless steel. The solid steel bracelet closes with a one-touch triple lock, and the entire watch weighs 115.5 grams. Sapphire crystal with anti-reflective coating covers the dial. The proportioned lugs and relatively low profile keep the functional design cohesive.
