The men's Citizen Promaster Sky Radio Controlled AT8300-58L follows on from Citizen's bestselling AS4020-52E and its successor, the CB5860-86E. It is made for those who value precise timekeeping, with multi-frequency radio-controlled timekeeping. This model is powered by solar energy (Eco-Drive), eliminating the need to replace the battery. Its pilot-style design makes it suitable for use in the skies, but it is also well suited to everyday wear.
The case and steel strap of the Citizen AT8300-58L are made of stainless steel. Inside the case is the in-house Citizen H800 movement, which offers precise timekeeping thanks to the Radio-Controlled system, synchronising the time via a radio signal. Other functions include a battery charge indicator, overcharge protection, an insufficient charge warning indicated by the seconds hand moving in two-second increments, and a power-saving mode. The watch also features a stopwatch accurate to 1/20 s and a 24-hour subdial at 9 o'clock. The date and day of the week indicators are also practical. The slide rule bezel can be used for simple slide rule calculations and to calculate the remaining fuel in an aircraft.
This model is powered by Eco-Drive technology, using a light-recharged battery with a power reserve of up to 6 months (10 months in power-saving mode). This eliminates the need to replace the battery. The watch has a water resistance of 200 m, making it suitable for contact with water, including swimming and diving. Water resistance is supported by a screw-down crown. The dial is protected by a sapphire crystal, which provides maximum protection against scratches. An anti-reflective coating (on the inside in this case) provides maximum legibility even in bright sunlight.
We provide a 7-year warranty on Citizen watches.
