Originally designed for underwater exploration, the Longines Legend Diver is equally at home on land or underwater. With its timeless design and cutting-edge performance, it has been a true icon of watchmaking since 1959. At first glance, it is distinctive because of its two crowns and internal rotating bezel. Invented by Longines, the position of the bezel inside the case protects it from accidental manipulation and shocks that could alter its settings. These true tool watches are powered by exclusive Longines calibres equipped with a silicon balance-spring.
