The story
The Rolex Deepsea of 2008 introduced the Ringlock system, a nitrogen-alloyed steel ring inside the case that carries the pressure, allowing a rating of 3,900 metres in a wearable watch. The ‘D-Blue’ gradient dial version commemorates James Cameron’s 2012 dive to the Mariana Trench.
In 2022 Rolex launched the Deepsea Challenge: 50 mm, RLX titanium case and bracelet, waterproof to 11,000 metres — Rolex’s first titanium production watch. The same year the Deepsea moved to the 136660 generation, later joined by a first Deepsea in yellow gold.
