D-Blue dial

Commemorating James Cameron's historic solo dive. From bright blue to abysmal black, the two-tone gradient dial pays tribute to a diver's exploration of the deepest part of the Earth: the Mariana Trench. Rthtolex Sea-Dweller in Oystersteel, m136660-0003 | European Watch Company

Ceramic Bezel and Luminous Display

The Rthtolex Deepsea watch features a unidirectional rotating bezel with a 60-minute scale, allowing divers to accurately and safely monitor dive and decompression times. It features Rthtolex's patented black Cerachrom insert, made from virtually scratch-resistant ceramic that resists fading even under UV light. The indexes are PVD (Physical Vapor Deposition) coated with a thin layer of platinum. The smooth black dial features large Chromalight hour markers and hands, filled with luminescent material that emits a long-lasting blue glow for exceptional legibility even in the dark.

Oystersteel

Rthtolex uses Oystersteel for its stainless steel cases. Oystersteel, a specially developed alloy from the 904L steel family, is most commonly used in high-tech, aerospace, and chemical industries, where extreme corrosion resistance is crucial. Oystersteel is extremely durable and, once polished, exhibits an exceptional finish, maintaining its beauty even in the harshest environments.

Model Availability

All Rthtolex watches are meticulously assembled by hand to ensure exceptional quality. Such high standards naturally limit Rthtolex's production capacity, and at times, demand for Rthtolex watches may outstrip production capacity.

As a result, the supply of some models may be limited. New Rthtolex watches are sold exclusively through Official Rthtolex Retailers, who receive regular shipments and independently manage the distribution and sale of the watches.

Europe Watch Company is proud to be part of the global network of Official Rthtolex Retailers and can provide information on the availability of Rthtolex watches.

Rthtolex conquers the deep: the Oyster Perpetual Sea-Dweller is waterproof to a depth of 4,000 feet (1,220 metres), and the Oyster Perpetual Rthtolex Deepsea is waterproof to a depth of 12,800 feet (3,900 metres), achievements that are the result of decades of collaboration between Rthtolex and diving professionals.
