Citizen Promaster Sikorsky Atomic Timekeeping JY8156-00L

The Citizen Promaster Sikorsky JY8156-00L takes its inspiration from the Sikorsky S-92, a helicopter used for search and rescue, transportation and other demanding missions. The blue dial and matching rubber strap, high-contrast red, yellow and white accents, and combination of hands and digital displays give it a cockpit-instrument character. But the real appeal is how much this watch can do.

More Than One Time Zone

The light-powered U680 movement combines traditional hands with digital displays so you can keep track of more than one clock. Select from 43 world cities for local time, keep a second time zone in view, or check Coordinated Universal Time (UTC), the common time reference used in aviation. Its radio-controlled atomic timekeeping can synchronize the watch with a compatible time signal when reception is available. The perpetual calendar also keeps track of changing month lengths and leap years.

Timing Tools You Can Actually Use

The chronograph measures elapsed time in 1/100-second increments for up to 24 hours, whether you're timing a short interval or a long journey. A separate countdown timer can be set for up to 99 minutes, and two alarms give you reminders independent of the main time display. A digital backlight helps you read the digital information in low light, while the power-reserve indicator shows how much stored energy remains.

Built for a Full Instrument Panel

All of that capability lives in a substantial 46 mm stainless-steel case with sapphire crystal, a blue rubber strap and 200-meter water resistance. Eco-Drive converts light into energy, so you don't need routine disposable-battery changes. This is a watch for someone who enjoys exploring a sophisticated instrument, not someone looking for a simple three-hand dial.

Our Take

We carry this edition because the S-92 connection suits the watch rather than simply decorating it. Its multiple time displays, UTC reference and separate timing tools make the aviation theme feel purposeful. The fun is learning what every part of that busy dial can do, then finding yourself using more of it than you expected.
