Citizen Radio Controlled Watch (limited edition) - JY8146-54E

Citizen SKY Series – 35th Anniversary Limited Edition JY8146-54E

Master time with precision, technology and sophistication

In celebration of the 35th anniversary of the legendary Promaster SKY series, Citizen presents the stunning JY8146-54E model – a global limited edition of just 5,600 numbered pieces. This is a true professional pilot’s watch, ideal for those who value high-performance functionality, refined aesthetics and cutting-edge technology.

Design inspired by the natural phenomenon “Midnight Sun”

With a robust case and modern architecture integrated into the bracelet, the design of this limited edition pays homage to the “Midnight Sun” – a phenomenon in the polar regions where the sun never sets during the summer. The dark grey color evokes nocturnal elegance and is complemented by subtle details that evoke the exclusivity of the series. The 35th anniversary logo is engraved on the case back of the watch.

Advanced technology for maximum precision

At the heart of the JY8146-54E is the acclaimed Caliber U680, a radio-controlled Eco-Drive movement that automatically synchronizes with the world’s most accurate atomic clocks (Germany, Japan, the US and China). Even without a signal, it maintains an impressive accuracy of ±15 seconds per month.
