Call Sign

The Discovery Collection was built around a simple idea: give pilots what they actually need, without the clutter.

Aviation-inspired design meets purposeful functionality, with dual timekeeping, a signature crescent Zulu (GMT) dial, Swiss-made quartz movement, sapphire crystal, 316L stainless steel, and Super-LumiNova on every timepiece.

Designed for the cockpit. Refined for everywhere else.

Comfortable on the wrist, easy under a cuff, and free from the snags and bulk of oversized cases.

A little throwback to Indy with Louis Foster and the Discovery Gold. 🏁

Call Sign is built to keep up with the moments that move you.

The Brothers is a limited-edition tribute to Wilbur and Orville Wright and the breakthrough that changed aviation forever.

Limited to 200 individually numbered pieces, each watch honors the Wright brothers’ pioneering spirit, with a caseback featuring their own hand-drawn wing-warping design, a detail rooted in the innovation that made controlled flight possible.

A timepiece built to remember where flight began.

The journey doesn't stop when the sun goes down. Powered by X1 Grade Super-LumiNova®, the Discovery Lume delivers exceptional brightness and long-lasting visibility so clarity is there when you need it most.

Built for those who keep their eyes on the next turn.

On the track, every second counts. Off it, keeps it just as sharp with Call Sign.

Precision never goes out of style. 🏁

On his wrist: Discovery Gold

Clean design, dual timekeeping, and a slim profile made for everyday wear.

The watch pictured here is the Cadre GMT, one of the watches representing the next chapter of Call Sign.

Automatic. True GMT. Purpose built. Distinctly ours.

And now part of a year in which Call Sign has been nominated for American Watch Brand of the Year by WatchPro.

We’re proud of how far the company has come.

We’re even more excited about what comes next.
