Our passion for aviation, adventure, and exploration drives everything we do. Hadley Rille builds high-quality precision Swiss timepieces for those who push boundaries and expand the envelope.

John Hadley pushed the boundaries throughout his professional life. Hadley was a respected inventor and mathematician. He made significant improvements in accuracy and power to the reflecting telescope for use in astronomy.

In 1730 John Hadley invented the Hadley Quadrant, a double reflector precision instrument used for nautical navigation. Hadley’s Quadrant was a trusted tool for explorers and adventurers alike to navigate their vessels safely to destinations around the world.

Timeless Aviator Spirit is an attribute and an attitude. It is a sense of adventure, exploration, and desire to push the boundaries of what is possible. An ambition to cut a new path and an eagerness to utilize all of one’s skill sets to get there. The arrogance to believe, the confidence to act, and the humility to achieve. Times change but the Timeless Aviator Spirit stays the same.

To commemorate his contributions to science and exploration Hadley Rille, a steep-walled valley that winds 100km across the surface of the moon, was named in his honor on the lunar surface. The rille was formed by ancient lava flows early in the Moon’s history and is believed to be one of the most geologically significant lunar regions.

In July 1971, American astronauts gazed down into the unexplored rille for the first time. Hadley’s passion for exploration and adventure laid the foundation for exploring the far reaches of Earth and beyond. This same passion propels Hadley Rille today. #TimelessAviatorSpirit
