CITIZEN AT8304-57A Promaster Sky Radio Controlled

The new Promaster Sky Global Radio Controlled brings professional aviation design to the wrist with precision and power. Built in gray ion plated stainless steel with a sharply finished triple link bracelet, this 41mm timepiece is water resistant to 200 meters and ready for every mission. Its pilot inspired dial features luminous hands and markers that stand out against a gray background, ensuring quick readability in all conditions. Surrounding the display is an aeronautical slide rule scale operated by the 7 o’clock crown, while a date window at 3 o’clock adds everyday practicality. Advanced functions include world time across 26 cities, a perpetual calendar with day and date display, 12 and 24 hour timekeeping, chronograph capability, and a power reserve indicator.

Powered by Eco-Drive, it draws energy from any light source, eliminating the need for battery changes.

This radio-controlled timepiece ensures unparalleled accuracy by automatically adjusting the time and calendar through local time signals in four different regions.

With Caliber H800 at its heart, this watch is the perfect fusion of innovative technology, bold style, and reliable performance for modern aviators.
