Ralf Tech WRX Stardust Limited Edition

The new WRX STARDUST and ROCKDUST – timepieces between ocean and cosmos

RALF TECH stays true to its tradition and presents with the new WRX STARDUST and ROCKDUST two exceptional wristwatches inspired by the unexplored depths of the seas to the vastness of space. These models were developed in collaboration with the Centre National d''Études Spatiales (CNES) and build on the insights of the WRX Space Millennium introduced in 2024. They combine the proven shape 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 dial with its micro-grained texture 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.

Heart of the 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 and achieves an impressive autonomy of up to 100,000 hours – equivalent to nearly 12 years of runtime. This surpasses conventional movements by a wide margin and makes the WRX STARDUST and ROCKDUST ideal companions for extreme missions, whether on Earth or in space.

Extremely durable for any challenge

These timepieces are not only stylish accessories but were specifically designed for use under extreme conditions. Their 47.5 mm large case together with a 5.9 mm thick, domed sapphire crystal offers unparalleled resistance to shocks, scratches, and pressure conditions. The unidirectional 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 reliable companions even on 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 – a service is only required after 10 years.

Exclusive equipment and limited edition

Each watch features a dial with green glowing SuperLuminova® C5 indices, a screwed crown, and a case back engraving with individual serial number. The Ceramfine® bezel with luminescent marker emphasizes high functionality and facilitates reading underwater. The design is complemented by a high-quality anthracite calf leather strap, additionally equipped with a silicone-coated lining. Thanks to a strap width of 26 mm and a solid 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 and are thus exclusive collector's items for discerning watch enthusiasts. Each watch is manufactured in France and represents a perfect combination of aesthetic excellence and technical innovation.
