OverviewWhat matters most about this product
Matte white with full SuperLuminova lume treatment makes this Call Sign Discovery GMT one of the most legible watches in its class, day or night. The 42mm PVD stainless steel case is built to the same 100 meter standard as the rest of the Discovery line, and the dual AR sapphire crystal keeps the luminous dial front and center without glare. The crescent GMT window is subtle when you don't need it and precise when you do, letting wearers track a second time zone without adding visual noise.
SuperLuminova markers and hands do the heavy lifting after sunset, and 40 months of power reserve means this is the watch you grab on the way out the door and never have to think about again. A serious watch for people who move with purpose.
