The addition of chronograph models represents a natural evolution of the Steel Colormark Series. The rugged 44-mm stainless steel case is designed to stand up to extreme conditions. Its unidirectional ratcheting bezel and highly scratch-resistant tempered mineral glass crystal protect the chronograph dial, which displays elapsed time up to 12 hours. Its color-coordinated numerals, bezel markings and hands are hallmarks of the Luminox Colormark collections. The series has a screw-down crown and caseback ensuring water resistance to 200 meters and is available on a solid-link stainless steel bracelet or a signature polyurethane strap featuring the Luminox shield.
