The Colormark concept is now available in steel watches. Given the outstanding success Luminox has enjoyed with its polymer series, it was only a matter of time before steel versions were to be added. The 44mm Steel Colormark series is comprised of 4 models, three with black dial, one with silver, and all with colored markings. All feature a their own night illumination color pattern, with the hour and minute hands glowing in blue and the hour markers glowing in blue and yellow.
