All about the Ralf Tech WRX Rockdust Limited Edition
The new WRX STARDUST and ROCKDUST – Timepieces between Ocean and Cosmos
RALF TECH remains true to its tradition and presents the new WRX STARDUST and ROCKDUST, two exceptional 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 on 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 striking appearance but also guarantee extreme durability. The dial, with its micro-grained structure, is reminiscent of cosmic surfaces – deep black for the STARDUST, chocolate brown for the ROCKDUST. The two-layer sandwich construction ensures excellent legibility, 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 – 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 Robust for Every Challenge
These timepieces are not just stylish accessories; they were specifically designed for use in extreme conditions. Their 47.5 mm case, together with a 5.9 mm thick, curved sapphire crystal, offers unparalleled resistance to shocks, scratches, and pressure. 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 defy extreme environmental conditions, while their innovative encapsulation system ensures long-lasting water resistance – service is only required after 10 years.
Exclusive Features and Limited Edition
Each watch features a dial with green luminous SuperLuminova® C5 indices, a screwed-down crown, and a case back engraving with an individual serial number. The Ceramfine® bezel with a luminescent marker emphasizes its high functionality and facilitates readability underwater. The design is complemented by a high-quality anthracite calfskin strap, which is also equipped with a silicone-coated inner 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.

RALF TECH WRX ROCKDUST & STARDUST Test
RALF TECH stellt seine neuen WRX-Modelle ROCKDUST & STARDUST. Die zu je 100 Stück limitierten Sondermodelle sind „von den Tiefen des Ozeans bis in die unendlichen Weiten des Weltraums“ inspiriert. Ich möchte ihre Vorstellung vor allem dazu nutzen, dir mehr über die vielleicht wichtigste Uhr von RALF TECH zu erzählen.
My personal view on the Ralf Tech WRX Rockdust Limited Edition
"RALF TECH hebt vor allem die besondere Gestaltung der Zifferblätter seiner neuen WRX hervor. Die Inspiration von Meteoriten, Mondgestein und Marsboden sind in meinen Augen ein schönes Gimmick. Die wirklichen Highlights der WRX erkennt man allerdings erst auf den zweiten Blick, da sie für das Auge weitestgehend unsichtbar sind. Da wäre zum einen das Gehäuse, das mit seiner robusten Bauweise jeder äußerlichen Einwirkung trotzt. Zum anderen zeichnet sich die WRX durch ihr innovatives Mikrohybridwerk aus. Beide Aspekte sorgen dafür, dass die RALF TECH WRX eine unglaublich leistungsfähige und zugleich unkomplizierte Uhr für professionelle Zwecke ist, die einmal im Jahrzehnt (!) gewartet werden muss."

About David from WATCHDAVID
Behind WATCHDAVID.SHOP, I, David Drilling, stand as a true watch enthusiast, watch photographer, and independent tester. Since 2018, I have been providing honest wear reports on my channels. In my shop, I exclusively sell watches whose quality and history I have personally verified. No anonymous mass-produced goods, but personal expertise.
Shipping & No Import Charges
Shipping within Germany and the EU is completely free for you and fully insured via DHL or FedEx Express. Important for you: There are guaranteed to be no import duties, taxes or hidden fees. The exact delivery time for your model will always be transparently displayed directly above the "Buy" button.
Cancellations & Free Returns
You can easily cancel your purchase within 14 days. Unlike other retailers, I will cover the full cost of your return shipping within the EU. Simply send me a short email to david@watchdavid.com and I will send you your free DHL return label. It doesn't get any more risk-free than that.
Authenticity & Condition of the Watches
I guarantee you 100% that all watches offered are unworn, brand new original goods. In the shop, I strictly differentiate between regular new goods directly from the manufacturer and exclusive photo watches. Photo watches are models that I have used for my videos or photos, or that come from a return. I sell them absolutely honestly as used and significantly reduced – but the full manufacturer's warranty only begins on the day of your purchase!
Warranty & David's "All-Round Carefree Service"
Every watch comes with the full, international manufacturer's warranty (at least 2 years). In the event of a warranty claim, you'll have absolutely no stress: I'll handle all communication with the brand and organize insured round-trip shipping for you. Even after the warranty period expires, I remain your personal point of contact for service inquiries.
Quality Control
Mechanical watches are fascinating masterpieces. Before dispatch, each watch undergoes a thorough optical and mechanical final inspection. Should a problem ever arise despite our secure transport protection, please inform me immediately by email. I will promptly arrange for a quick, uncomplicated replacement.
