CASE BACK ENGRAVING

Your watch, your mark. Every Discovery includes complimentary engraving—two lines, up to 12 characters each. Add your name, call sign, airmen #, or a message that makes it unmistakably yours.

THIN PROFILE

We don’t do bulky. Pilots told us they wanted a watch that worked with them, not against them. That’s why we designed ours with a slim, low profile—comfortable on the wrist and free from the snags that come with oversized cases.

GMT

GMT, simplified. Instead of a cluttered fourth hand, we built a clean 24-hour wheel. The result is quick, intuitive reading—no confusion between local and global time, just clear function with a distinctive look.

100M WATER RESISTANCE

Built for real-world conditions. With Viton® seals and gaskets, every Call Sign watch is engineered for durability and tested to 10 ATM water resistance. Ready for the cockpit, the ramp, or wherever your journey takes you.

x1 grade Super-LumiNova®

X1 Grade Super-LumiNova® is the highest-performance luminous material available, engineered to deliver brighter, longer-lasting afterglow than standard Super-LumiNova. Compared to lower grades and other lume options, X1 maintains visibility deep into the night, retaining up to 60% more brightness after extended hours in darkness. It’s the benchmark choice for premium timepieces where legibility and reliability matter most. This lume comes standard on all Call Sign timepieces.

Its Your time

Call Sign is built for everyday life—stylish enough for work or a night out, yet durable and practical for travel and adventure. It’s a watch that feels personal, with details that connect to your story and remind you of where you’ve been. More than just keeping time, it’s made to be worn, enjoyed, and lived in.
