Product Description

The Citizen Promaster SKY JY8074-11X is a professional aviation watch built for explorers who constantly push beyond everyday boundaries. Inspired by the concept “The Moment of Adventure”, the watch represents the spirit of discovering adventure even in ordinary moments.

As part of the Citizen Promaster SKY Series, this pilot watch is designed for global travelers, outdoor adventurers, and aviation enthusiasts who demand precision, durability, and advanced functionality.

Powered by Citizen Eco-Drive technology, the watch converts both natural and artificial light into energy, eliminating the need for battery replacements. Once fully charged, it can run for up to 3.5 years in power-save mode, ensuring reliable long-term performance.

The watch automatically synchronizes with radio time signals from Japan, China, the United States, and Europe, ensuring highly accurate timekeeping based on atomic clock standards.

It also incorporates PerfeX technology, combining magnetic resistance, shock detection, and automatic hand correction to prevent time deviation caused by shocks or magnetic interference.
