Towards the 6 o’clock position, a namesake Northern Hemisphere disc rotates counterclockwise, with the detail showcasing the world time with a map-inspired design.

Other standard and advanced functions of the watch include running hours and minutes, date indication, power reserve indication, world time, and a slide rule bezel function. This distinctive sports watch utilizes our proprietary Eco-Drive technology that’s sustainably powered by any light and never needs a battery. Water resistant up to 200 meters. Caliber H864.
