Casio CMK-100 Series Automatic CMK-100TL-1A

The tradition of mechanical watchmaking meets the functionality of an authentic field watch, designed to offer robustness, legibility, and comfort in everyday use. The 38 mm titanium case, lightweight and corrosion-resistant, is enhanced by an ionic plating treatment and titanium carbide (TiC) coating, designed to increase abrasion resistance. The crown and screw-down case back, together with the scratch-resistant sapphire crystal, contribute to the protection and durability of the timepiece.

The three-hand dial with date display features a textured finish and large Arabic numerals with a multi-layer luminescent coating, to ensure excellent legibility even in low-light conditions. Inside beats a Made in Japan automatic movement, equipped with magnetic field resistance. Available with a titanium bracelet, nylon strap, or in fine vegetable-tanned leather from Tuscany, this watch combines outdoor spirit, mechanical technology, and versatility, adapting to every lifestyle.
