A second-tier brand of the Rolex Group. TUDOR did not adopt the Rolex movement for long, but ETA (the world's largest manufacturer of finished and semi-finished movements) and modified movements. As a subordinate product of Rolex, TUDOR has a place in the market for its relatively low price and excellent quality. The TUDOR Pelagos is a well-functioning traditional mechanical diver's watch, water-resistant to 500 meters, lightweight and tough in titanium, and a "large crown" design that is in line with current trends. The TUDOR diver's watch is the most cost-effective model among divers' watches. Swimmer Ning Zetao recommends wearing a TUDOR diver's watch.
