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

The tradition of mechanical watchmaking meets the spirit of classic field watches, with a design created to combine robustness, legibility, and everyday comfort. The 38 mm titanium case, lightweight and corrosion-resistant, features an ion-plating treatment and a titanium carbide (TiC) coating designed to increase abrasion resistance. The crown and screw-down case back, together with the scratch-resistant sapphire crystal, ensure a solid structure and greater protection.

The three-hand dial with date display features a textured finish and large Arabic numerals with a multi-layer luminescent coating, for excellent legibility even in low-light conditions. At its heart beats a Made in Japan automatic movement, equipped with magnetic resistance.

Available in three different configurations: integrated titanium bracelet, lightweight and comfortable, durable nylon strap, or vegetable-tanned Tuscan leather strap, designed to develop a distinctive shine and an increasingly personal character over time. A versatile automatic watch that interprets military and outdoor design through refined materials and contemporary technical solutions.
