Our inspiration for the Redwood Pilot A-13 watch would go on to become one of the most iconic aircraft instrument designs of the 20th century. Interpreted as a wristwatch with rugged specifications, it is ready for anything you throw at it. A very capable tool watch in its own right, the A-13 is a piece of aviation history on your wrist.
At the heart of the Pilot A-13 Quad-Pulse beats the Seiko VH31—a movement that brings the best of both worlds. With its smooth sweeping seconds hand ticking four times per second, it has the visual rhythm of an automatic, minus the maintenance. No winding, no adjustments. Fewer moving parts mean greater reliability, especially in the field. It’s the kind of movement you want when failure isn’t an option.

PILOT WATCH FROM 1964:
THE A-13 QUAD-PULSE
Heritage-Inspired. BATTLEFIELD-Ready. Adventure-Proven.
THE MOST ICONIC AIRCRAFT INSTRUMENT
DESIGN OF THE 20TH CENTURY
Built for the cockpit
In 1964, the Department of Defense issued MIL-C-6499—a no-nonsense spec for a mechanical aircraft clock that demanded razor-sharp legibility: bold numerals, oversized hands, and a stepped dial with a raised outer track to reduce parallax.
The forthcoming Redwood Pilot A-13 draws its bloodline from this legendary instrument, one of the 20th century’s most iconic aviation designs. Reborn as a wristwatch with battle-ready specs, the A-13 thrives in the harshest conditions. It’s not just a timepiece—it’s a combat-tested design that carries aviation history on your wrist.
Mil-Spec DNA. Modern Muscle.
THE QUAD-PULSE MOVEMENT
Smooth Sweep. Aircraft Tough.
At the heart of the A-13 Quad-Pulse beats the Seiko VH31—a movement that brings the best of both worlds. With its smooth sweeping seconds hand ticking four times per second, it has the visual rhythm of an automatic, minus the maintenance. No winding, no adjustments. Fewer moving parts mean greater reliability, especially in the cockpit. It’s the kind of movement you want when failure isn’t an option.
Chronometer-Level Accuracy. Zero Hassle.
The Quad Pulse mechanicals don’t just look smooth—they run with precision no mechanical movement can match. With an accuracy of ±15 seconds per month, it outperforms high-end automatics and certified chronometers that cost 10 times more. No guesswork—just dependable timekeeping whether you're on the move or off the grid. For a watch built to take a beating, that kind of precision isn’t just impressive—it’s essential.
Mission-Ready. Always On.
The A-13 Quad-Pulse isn’t just built to take a beating—it’s built to be there when you need it, no matter what. Powered by a precise quartz movement, it runs for two full years on a single battery. No winding, no maintenance. Whether it's your daily companion or your backup on the road, it’s always on mission—reliable, accurate, and ready for action the moment you strap it on.
From Aircraft Panel to Your Wrist
STEPPED DIAL, STEEPED IN LEGEND
Legibility wasn’t optional—it was mission-critical. The A-13 spec called for an aircraft clock that could be read at a glance, even under G-force and glare. The Redwood A-13 Quad-Pulse delivers: bold numerals, a high-contrast layout, and a raised outer track that eliminates error when speed matters most. The sword-style hands echo the original cockpit instruments, while the luminous-tipped second hand gives instant confirmation that your movement is operating.
GLOW IN THE DARK
Original A-13 clocks relied on radioactive tritium for glow-in-the-dark visibility. The A-13 Quad-Pulse upgrades that legacy with non-radioactive Super-LumiNova, offering modern performance without the hazards. White by day and blazing green after dark, it lights up your mission when the sun goes down. All three hands and all 12 hour markers are coated for quick, reliable reading—no matter how deep the night.
Built Like They Used To — Only Stronger.
Rugged Form. Combat Function.
Purpose-built like the original—but sized for the field. The Redwood A-13 dials down the cockpit-sized 60mm spec to a wearable 42mm, keeping the military spirit while suiting everyday missions. Its all-stainless steel case is fully brushed to kill glare, and those oversized lugs? Drilled for fast strap changes and built to take a beating. Topped off with an oversized screw-down crown, this is a true tool watch—ready to deploy wherever you go.
Armor for Your Dial
The Pilot A-13 is armored with a flat sapphire crystal—second only to diamond in hardness and built to take a beating. Its low profile minimizes snags and scratches, while custom seals and a solid 1.8mm thickness ensure it stays watertight under pressure. Whether you're diving deep or getting through the dirt, your view stays sharp and mission-ready.
Locked Down. Ready for Anything.
The original A-13 clocks had to endure the chaos of the cockpit—dust, moisture, pressure shifts. The A-13 Quad-Pulse keeps that same no-nonsense spirit alive with full 100m (330ft) water resistance, thanks to an oversized screw-down crown, sealed caseback, and high-grade polymer gaskets. It’s built to survive turbulence, downpours, or deployment—wherever your mission takes you.
