The Citizen Promaster Sky AT8396-59L is a high-precision radio-controlled solar chronograph for men, combining cutting-edge technology with a robust pilot's design. The Super Titanium case, measuring 40.5 mm in diameter and 10.4 mm in thickness, provides an exceptionally lightweight yet highly resilient wearing experience. The deep-blue dial features white hands and luminous indices, ensuring excellent legibility even in poor visibility conditions.

Powering the Citizen AT8396-59L is the Eco-Drive calibre H804, which converts light energy into electrical energy, eliminating the need for battery changes permanently. Via radio time signal, the watch automatically synchronises to the precise time across multiple time zones. Complications include a chronograph, date, 24-hour display, and a 26-zone world time function, making it the ideal companion for the well-travelled gentleman. The scratch-resistant, anti-reflective sapphire crystal protects the dial from scratches and glare. With water resistance to 20 bar, the Promaster Sky is also suited for demanding water sports activities.
