Ralf Tech WRX Stardust Limited Edition

The New WRX STARDUST and ROCKDUST – Timepieces Between Ocean and Cosmos

RALF TECH remains true to its tradition, presenting the new WRX STARDUST and ROCKDUST – two extraordinary wristwatches inspired by the unexplored depths of the oceans and the vastness of space. These models were developed in collaboration with the Centre National d'Études Spatiales (CNES) and build upon the insights gained from the WRX Space Millennium introduced in 2024. They combine the proven form of the WRX Electric with state-of-the-art technology and a new, unique design.

Innovative Design and Uncompromising Robustness

The WRX STARDUST and ROCKDUST impress with their sandblasted cases made of 316L surgical steel, which not only provide a distinctive look but also guarantee extreme durability. The micro-grained dial resembles cosmic surfaces – deep black on the STARDUST, chocolate brown on the ROCKDUST. The two-layer sandwich construction ensures excellent readability, both in daylight and in dark environments.

The Heart of Technology: The RTE001 Micro-Hybrid Movement

Inside these exclusive timepieces works the Swiss-developed RTE001 micro-hybrid movement. This innovative technology combines the precision of a quartz movement with the robustness of mechanical components, achieving an impressive autonomy of up to 100,000 hours – which corresponds to almost 12 years of running time. This far surpasses conventional movements, making the WRX STARDUST and ROCKDUST ideal companions for extreme missions, whether on Earth or in space.

Extremely Durable for Every Challenge

These timepieces are not only stylish accessories but were specifically designed for use under extreme conditions. Their 47.5 mm case, together with a 5.9 mm thick, domed sapphire crystal, offers unparalleled resistance to impacts, scratches, and pressure conditions. The unidirectional rotating ceramic bezel with 120 clicks meets the ISO 6425 standard and ensures precise dive settings.

Furthermore, the watches are water-resistant up to 1000 meters (3300 feet), making them a reliable companion even during the deepest dives. With a temperature resistance from -50°C to +55°C, they withstand extreme environmental conditions, while their innovative encapsulation system ensures long-lasting water resistance – only after 10 years is servicing required.

Exclusive Features and Limited Edition

Each watch features a dial with green luminous SuperLuminova® C5 indices, a screw-down crown, and a case back engraving with an individual serial number. The Ceramfine® bezel with a luminous marker underscores the high functionality and facilitates readability underwater. The design is complemented by a high-quality anthracite calfskin strap, additionally equipped with a silicone-coated lining. Thanks to a lug width of 26 mm and a massive 26 mm pin buckle, the watch sits securely on the wrist.

The WRX STARDUST and ROCKDUST are produced in a limited edition of only 100 pieces, making them exclusive collector's items for discerning watch enthusiasts. Each individual watch is manufactured in France and represents a perfect combination of aesthetic excellence and technical innovation.
