Explorer is a no-nonsense tool designed for polar expeditions, specifically focused on "time checking" in harsh environments.
Explorer I is available in 36mm and 40mm sizes and features a unique Chromalight luminous material that maintains its glow for extended periods even in dark environments.
Explorer II features a 24-hour bezel, a large orange GMT hand, and Paraflex shock absorbers, maximizing its shock resistance.
Both models share a clear design philosophy: either they eliminate the calendar mechanism (I) or they feature a robust crown guard (II), resulting in unparalleled reliability as instruments for professionals.
