Powered by a self-winding automatic movement, the CASIO AUTOMATIC collection brings the artistry of mechanical watchmaking into everyday wear. Inspired by classic field watches designed for purpose and reliability, the CMK-100 combines exceptional legibility, all-day comfort and a timeless design that transitions effortlessly from outdoor adventures to daily life. Its lightweight titanium case is naturally resistant to corrosion and enhanced with ion plating and titanium carbide (TiC) coating for added durability. A screw-lock crown and case back help maintain a secure seal, while a scratch-resistant sapphire crystal provides dependable protection. The 38mm case and slim 11.4mm profile sit comfortably on the wrist, complemented by a flat-top bezel and textured crown detailing that reflect its rugged field watch heritage. At the heart of the watch is a Made in Japan automatic movement with magnetic resistance, driving a clean three-hand display with date function. The subtly textured dial adds depth and character, while oversized Arabic numerals feature multiple layers of luminescent coating for a bold, highly legible finish in any environment. Choose from three strap options to suit your lifestyle. The titanium bracelet offers a lightweight, integrated look that pairs perfectly with the case. The durable nylon strap delivers a classic field-watch aesthetic with a soft, flexible feel, while the vegetable-tanned leather strap, crafted from Tuscan leather, develops a unique patina over time for added character and comfort.

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.
