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.

Specifications
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.
Furthermore, the crown and case back both feature a screw-lock construction to ensure a tight seal for the case. 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.
