The Editorial
Atomic-synced precision from six radio towers worldwide. The Skyhawk combines Eco-Drive solar power with radio-controlled timekeeping — the most accurate watch in the collection, set by satellite signals, powered by light.
Why This Watch
A piece worth
acquiring.
Ideal for
The pilot. The tech enthusiast. The traveler who wants atomic-precision timekeeping without ever setting the watch manually.
The Skyhawk syncs to atomic time signals from six radio towers worldwide — WWVB (US), JJY (Japan), MSF (UK), DCF77 (Germany), BPC (China). Combined with Eco-Drive solar power, it never needs a battery and never loses accuracy. Slide-rule bezel, world time, chronograph, perpetual calendar — it's the most functional watch in the entire collection.
Collector's Note
This is the watch NASA engineers wear when they're not wearing a Speedmaster. The atomic sync is genuinely useful — you'll never set this watch.
