Citizen Pro Master Sky

Citizen's ProMaster Sky U830 represents a significant leap in pilot watch engineering, powered by the newly developed in-house calibre U830. This 43mm stainless steel instrument combines aviation heritage with cutting-edge technology, featuring a high-resolution MIP display that delivers superior outdoor legibility and intuitive world time navigation across 43 zones—essential for globe-trotting aviators and professionals alike. The U830 movement distinguishes itself through comprehensive functionality: dual alarms, chronograph with extended 40-hour measurement, permanent UTC display at 12 o'clock, and a real-time energy indicator tracking seven days of Eco-Drive light conversion. The slim slide rule bezel and wing-inspired lugs reinforce its aeronautical DNA, while the anti-reflective sapphire crystal and grey dial with applied indices ensure precision readability in demanding conditions. Water-resistant to 20 bar and built from solid stainless steel with a secure double-push bracelet clasp, this watch delivers exceptional durability. The standout feature: a 360-day power reserve with three-year dark storage capability—eliminating battery changes entirely. For discerning collectors who demand both technical sophistication and timeless design, the ProMaster Sky U830 sets a new standard.
