• Global Radio-Control (A-T): Automatically receives time signals from atomic clocks in five regions: North America, Europe, China, and two in Japan (Fukushima and Kyushu). This ensures the watch is accurate to within one second every million years.
• Vintage Cartography Aesthetic: The font used for city names and the UTC disc is inspired by 16th-century maps from the "Age of Discovery," giving it a unique blend of modern tech and historical flair.
• Aviation Slide Rule: The bidirectional rotating outer bezel serves as a manual flight computer for calculating speed, fuel consumption, and distance.
• Superior Legibility: Designed for cockpit use, it features oversized luminous hands and indices, plus a power reserve indicator and a perpetual calendar that correctly handles months of varying lengths (including leap years) until 2100.
• Northern Hemisphere Disc: Located at the 6 o'clock position, this rotating map disc allows you to estimate the time in various regions across the northern hemisphere. The disc's rotation is synchronized with the world time function.
