An Anchor System
Kumamoto was designed as a complete platform—end-links, clasp, and strap material engineered together for a seamless, integrated feel.
Kumamoto™ System

Seamless at the Lugs
Purpose-built end-links create a clean, continuous line from case to strap/bracelet—no awkward gaps, no generic fit.
Double Flip-Lock Security
A firm, reassuring close with refined tolerances. Built to feel precise every time you lock in—on steel or on rubber.
Refined, Not Flashy
Tool watch energy with premium execution—clean edges, tight fit, and a finish that looks sharp without shouting.
Kumamoto ™ CTS Rubber Strap
The Kumamoto ™ CTS Rubber Strap brings the precision and construction of the Kumamoto system to a straight-end, universally compatible format.
Built from premium FKM rubber and engineered with a cut-to-size (CTS) architecture, this strap delivers a tailored fit, refined hardware, and everyday durability — without requiring integrated end links.
This is Kumamoto performance, made universal.
Cut-To-Size Precision
Like the integrated Kumamoto models, this strap features a true CTS construction. The strap is trimmed to your exact wrist size and secured with a double flip-lock 316L clasp, creating a clean, balanced fit with no excess length.
The result is a deployant system that wears secure, streamlined, and purpose-built.
Solid 316L Double Flip-Lock Clasp
The Kumamoto CTS Rubber Strap is paired with a solid 316L stainless steel deployant clasp featuring a double flip-lock safety system.
Engineered for strength and long-term reliability, the clasp delivers a confident closure and refined mechanical feel while maintaining a slim wrist profile.
Premium FKM Rubber
Constructed from high-grade FKM rubber:
-
Resistant to heat, UV, sweat, and saltwater
-
Flexible and comfortable for all-day wear
-
Structured enough to hold shape over time
-
Designed for long-term durability
This is performance material — not silicone, not generic rubber.
Straight Ends. Broad Compatibility.
Unlike integrated Kumamoto end-link models, the straight-end design allows compatibility with a wide range of watches.
From modern dive watches to everyday tool watches, the Kumamoto CTS adapts cleanly while maintaining the precision and balance of the system.
Quick-Release Installation
Each strap includes premium quick-release spring bars for effortless installation and strap changes — no tools required.
Switch watches. Change colors. Adjust your setup in seconds.
