Automatic movement timepieces with enhanced field-watch practicality
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 lightweight, rust-resistant titanium case is finished with ion-plating (IP) and titanium carbide (TiC) coating to enhance abrasion resistance. The screw-lock crown and screw-back case help deliver 100-meter water resistance. Scratch-resistant sapphire crystal and other carefully considered details ensure reliable performance across a wide range of situations.
Powered by a Made-in-Japan automatic movement with magnetic resistance, the watch features a simple three-hand dial with a date display that blends naturally into everyday life. The lineup includes five distinctive models with titanium, cloth, and leather band options to complement active lifestyles.

Features
Titanium case balancing practicality and design
The case features a solid, well-balanced form with a flat-top, wide bezel. Despite the watch’s substantial presence, it maintains a comfortable size with a 38 mm case diameter and an 11.4 mm profile. The titanium case combines strength and lightness with outstanding corrosion resistance. IP treatment and TiC coating enhance abrasion resistance, delivering performance ready for all kinds of activities.
And the case back features a screw-lock construction to ensure a tight seal. Details such as the non-slip knurled finish on the sides of the crown illustrate the careful attention given to every part of the exterior.
Due to the screw-lock construction of the case back, the orientation of the logo and lettering on it may not match up perfectly with the dial.
Textured dial design delivering outstanding visibility
The dial boasts a finely textured finish created using a special stamping process. Combined with the simple layout featuring three hands and date display, it makes for an outdoor-inspired appearance. The large Arabic numerals are printed with multiple layers of phosphorescent paint to create a three-dimensional effect that blends naturally with the dial’s finish.
Three distinct band material options
The lineup consists of models with three different band materials. The titanium band complements the structural beauty of the case with a unified design, combining a substantial look with a lightweight, comfortable fit. The cloth band, a classic choice for a field watch, offers a soft, flexible feel along with excellent durability. The thick nylon material provides a secure fit on the wrist. The leather band, crafted from vegetable-tanned leather sourced from Tuscany, Italy, lends the watch a classic, refined look. Over time, it becomes more comfortable on the wrist while developing a rich luster and distinctive character.
Made-in-Japan automatic movement
The watch is driven by a Made-in-Japan automatic movement with magnetic resistance. The movement offers a power reserve of approximately 42 hours, delivering reliable performance from everyday wear to field activities.
Sapphire crystal
The scratch-resistant highly transparent sapphire crystal delivers excellent clarity and readability.
