CITIZEN PROMASTER SKY
Radio Controlled 41 mm
Pilot watches are usually equipped with numerous functions – and are therefore large in diameter. These instrumental timepieces often have a diameter of 43 mm or more. CITIZEN is breaking this rule and is showing with the new PROMASTER SKY RC 41 that it's totally possible to have features such as 26 local times, a chronograph, a light-powered and radio-controlled Eco-Drive movement (Radio Controlled) and an internal slide rule bezel for flight-related calculations can be clearly and functionally integrated into a 41 mm case.
The new AT8304-57W model is radio-controlled and equipped with an internal slide rule bezel for calculating fuel consumption and tank capacity. These settings can be adjusted using a second crown at the 8 o'clock position. Inside, the in-house calibre H800 works, which can pick up radio signals from an atomic clock and keeps time down to the second.
Even when there is no signal, the accuracy is +/-15 seconds per month. In addition, it features scratch-resistant sapphire glass with anti-reflective coating, magnetic resistance and water resistance up to 20 bar.
