Powered by an automatic movement, CASIO AUTOMATIC timepieces bring mechanical watch craftsmanship to everyday life. A field watch rooted in the tradition of durable timepieces conceived as tools, the CMK-100 balances excellent readability, a comfortable fit on the wrist, and a design that fits naturally into daily life.

The case is crafted from lightweight, rust-resistant titanium and finished with ion plating and titanium carbide (TiC) coating to enhance abrasion resistance. Both the crown and case back feature a screw-lock construction for a tight seal, while the scratch-resistant sapphire crystal enhances durability. The comfortable 38 mm case diameter and 11.4 mm profile are paired with a flat-top, wide bezel and a knurled finish on the sides of the crown for an outdoor-inspired design.

The simple three-hand dial with date display is powered by a Made-in-Japan automatic movement with magnetic resistance. A delicately textured finish adds depth to the dial, while large Arabic numerals are printed with multiple layers of phosphorescent paint to create a raised appearance for excellent readability.

There are three band options available to complement any active lifestyle. The titanium band pairs seamlessly with the case for a unified look while providing a lightweight, comfortable fit. The cloth band, a classic choice for a field watch, is made from durable nylon with a soft, flexible feel. The leather band uses vegetable-tanned leather sourced from Tuscany, Italy. Over time, it develops a rich luster and distinctive character while becoming even more comfortable on the wrist.
