The Citizen Skyhawk Radio Controlled JY8100-80L watches are made for lovers of accurate time, displayed by multi-frequency radio-controlled timekeeping. This model is powered by solar energy (Eco-Drive) and thanks to the use of titanium Super Titanium™, it is exceptionally comfortable to wear. It is an aviation-inspired model, but it also serves very well for everyday wear.
The case including the strap of the Citizen JY8100-80L watches is made of Super Titanium™, which ensures low weight and complete anti-allergenic properties. Inside this case works the in-house Citizen U680 movement, which offers absolutely accurate time thanks to the Radio-Controlled system, i.e. time synchronisation via radio signal. You can also rely on other functions, such as battery charge level indication, overcharge prevention, warning of insufficient charge by two-second jumps of the seconds hand, or switching to power-saving mode. You can also use the stopwatch, alarm, or the 24-hour sub-dial at the 12 o’clock position. Very practical is the date display and other functions on the digital part of the dial.
The drive of this model is provided by Eco-Drive technology, i.e. a light-charged rechargeable battery with a power reserve of up to 6 months and 42 months with power-saving mode activated. This eliminates the need to replace the battery. The water resistance of these watches is 200 m, so they can handle contact with water without any problem, such as swimming or diving. The dial is protected by a sapphire crystal, which provides maximum protection against scratches. Good legibility in bright light is ensured by an anti-reflective coating.
We provide a 7-year warranty on Citizen watches.
