Compact: Instrumental radio pilot watches

CITIZEN PROMASTER SKY Radio Controlled in 41 mm

Three Citizen watches with different colored faces and stainless steel bands.

Compact power: the new PROMASTER SKY in three versions

Pilot watches are usually equipped with numerous functions – and are correspondingly large in diameter. These instrumental timepieces often measure 43 mm and more. CITIZEN breaks with this rule and shows with the new PROMASTER SKY RC 41 that it is possible to create 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 accommodated in a 41 mm case.

The new SKY models are the perfect choice for pilots, adventurers and modern explorers, for whom CITIZEN has been developed watches for professional use in the PROMASTER SKY, LAND and MARINE series for over 35 years.

The compact pilot's chronographs are available in three versions: stainless steel with a black or blue dial, and a grey-coated version with a dark green dial. 

PROMASTER SKY 40 – CITIZEN's compact pilot's chronographs

CITIZEN presented the first SKY models with a similarly compact diameter back in spring 2025. However, these new models are now 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 ticks away, receiving radio signals from an atomic clock and keeping accurate 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.
