The men's Citizen Promaster Sky Eco-Drive Chrono CA4664-60X watch stands out for its attractive sporty design. This model is powered by solar energy (Eco-Drive), eliminating the need to replace the battery. Its pilot-style design makes it suitable not only for flying an aircraft, but above all for everyday wear.
The case and steel strap of the Citizen Promaster Sky Eco-Drive Chrono CA4664-60X watch are made of stainless steel. Inside the case is the in-house Citizen B620 movement, which has a light-recharged accumulator with a power reserve of up to 9 months and a low charge indicator. Its other functions include a stopwatch, a 24-hour subdial and a date display between 4 and 5 o'clock. The stopwatch features a smoothly moving seconds hand, allowing time to be measured to an accuracy of 1/5 s. The bidirectional rotating bezel features a slide rule, used by pilots to calculate the amount of fuel remaining.
The easy-to-read dial is protected by a sapphire crystal, which is highly resistant to scratches. An anti-reflective coating ensures excellent legibility even in bright sunlight. The watch has a water resistance of 200 m, so it can handle contact with water, including swimming and diving to approximately 20 metres.
We provide a 7-year warranty on Citizen watches.
