Tudor was established in 1926 by Hans Wilsdorf, the founder of Rolex, with a vision to create watches that offered the same reliability and precision as Rolex, but at a more accessible price point. Built with robust Swiss movements and housed in Rolex-quality cases, Tudor quickly earned a reputation for producing tool watches trusted by military units and professional divers around the world. In the 1950s and ‘60s, Tudor introduced iconic models like the Oyster Prince Submariner, worn by the French Navy, and carved out a legacy as a maker of rugged, no-nonsense timepieces built to perform under extreme conditions.

In recent years, Tudor has reemerged as one of the most exciting names in modern watchmaking. Collections like the Black Bay, Pelagos, and Ranger pay homage to the brand’s vintage roots while incorporating in-house calibers and contemporary design updates. The Black Bay Fifty-Eight, in particular, has become a collector favorite for its perfect blend of vintage proportions and modern engineering. With a design language all its own and a renewed focus on manufacturing independence, Tudor has established itself as far more than Rolex’s younger sibling—it’s a brand that balances heritage, innovation, and value with serious horological credibility.
