Citizen Promaster Sky RC 41 – Instrument watch with (small) format
Pilot's watches are typically equipped with numerous functions – and are correspondingly large in diameter. These instrumental timepieces often measure 43 millimeters or more.
Citizen breaks with this rule and proves with the new „Promaster Sky RC 41“ that it is quite possible to neatly and functionally accommodate features such as 26 local time zones, a chronograph, a light-powered and radio-controlled Eco-Drive movement (Radio Controlled) and an internal slide rule bezel for flight-related calculations in a 41-millimeter case.
The compact pilot chronographs come in three versions: in pure stainless steel with a black or blue dial, and in a grey coated version with a dark green dial.
High functionality in 41 millimeters
Citizen presented the first "Sky" models with a similarly compact diameter, the "Promaster Sky RC 41," back in spring 2025. However, the new 41-millimeter models are now radio-controlled and equipped with an internal slide rule bezel for calculating fuel consumption or tank capacity.
These settings can be adjusted via a second crown at the 8 o'clock position. Inside beats the in-house chronograph caliber H800, which can receive radio signals from an atomic clock and thus keeps accurate time to the second. Even without a signal, the accuracy is ±15 seconds per month.
Functionality includes a 24-hour display, low battery indicator, stopwatch, perpetual calendar, power reserve indicator, local time for 26 cities, world time, 180-day power reserve, 10-month power reserve in darkness, and solar power (Eco-Drive). It also features a scratch-resistant sapphire crystal with anti-reflective coating, magnetic resistance, and water resistance up to 20 bar.
