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 with the new WRX STARDUST and ROCKDUST two extraordinary wristwatches inspired by the unexplored depths of the seas and the vastness of the cosmos. These models were developed in cooperation with the Centre National d'Études Spatiales (CNES) and build upon 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 sturdiness
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 texture recalls cosmic surfaces – deep black on the STARDUST, chocolate brown on the ROCKDUST. The two-layer sandwich construction ensures excellent legibility, both in daylight and in dark surroundings.
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 sturdiness of mechanical components and achieves an impressive autonomy of up to 100,000 hours – which corresponds to nearly 12 years of running time. This surpasses conventional movements many times over and makes 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 specially designed for use under extreme conditions. Their 47.5 mm large case together with a 5.9 mm thick, curved sapphire glass offers unparalleled resistance to shocks, scratches, and pressure conditions. The one-sided rotating ceramic bezel with 120 clicks meets the ISO 6425 standard and ensures precise dive settings.
Furthermore, the watches are waterproof 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 guarantees long-lasting water resistance – a service is only required after 10 years.
Exclusive features and limited edition
Each watch features a dial with green glowing SuperLuminova® C5 indices, a screw-down crown, and a case back engraving with individual serial number. The Ceramfine® bezel with luminescent marker underlines the high functionality and facilitates reading underwater. The design is complemented by a high-quality anthracite calfskin 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 individual watch is made in France and represents a perfect blend of aesthetic excellence and technical innovation.

RALF TECH WRX ROCKDUST & STARDUST Test
RALF TECH presents its new WRX models ROCKDUST & STARDUST. The special editions, limited to 100 pieces each, are inspired "from the depths of the ocean to the infinite expanses of space." I especially want to use their introduction to tell you more about perhaps the most important watch from RALF TECH.
My personal view on the Ralf Tech WRX Rockdust Limited Edition
"RALF TECH primarily highlights the special design of the dials of its new WRX. The inspiration from meteorites, moon rock, and Martian soil is, in my eyes, a nice gimmick. However, the real highlights of the WRX are only recognized at second glance, as they are largely invisible to the eye. On the one hand, there is the case, which, with its robust construction, resists any external impact. On the other hand, the WRX is characterized by its innovative micro-hybrid movement. Both aspects ensure that the RALF TECH WRX is an incredibly powerful and at the same time uncomplicated watch for professional purposes, which only needs to be serviced once every decade (!)."

FAQs
About David from WATCHDAVID
My name is David and I have been deeply involved with watches for many years – not only as a dealer but especially as a tester, photographer, and classifier.
Since 2018, I have been running WATCHDAVID as an independent watch project with reviews, videos, and genuine wearing experiences. Many of the watches you find here I have worn myself – often for extended periods.
WATCHDAVID.SHOP is deliberately kept personal. I only sell watches that I truly stand behind – no anonymous mass products, no dropshipping, no “quick trends.” Experience, transparency, and honest assessment are my priorities.
And yes: I am not an anonymous seller. I like good food, sneakers, and photography – and I have a noted weakness for Kinder Chocolate.
If you have questions or are unsure, feel free to contact me directly. I respond personally.
Shipping & Insurance
Within Germany and the EU, I ship free of charge. Shipping is done via DHL and insured up to 500€, 2,500€, or 25,000€, depending on the watch value. The watches are thus always sufficiently insured.
The delivery time can be found in the description and/or under the shopping cart button. Some watches are only produced after ordering, others are brand new and, for example, only available in a few weeks (so-called PRE-SALE), etc...
Cancellation & Return Shipping
You can cancel your purchase within 14 days of receiving the goods.
I will cover the costs for the return shipping for you.
IMPORTANT: Do not send the watch back yourself, I will send you the free return label.
Please simply contact me for this. david@watchdavid.com
It is also important that the watch is unworn and free of signs of use. After successful inspection, I will refund you the purchase price. The refund will be made using the same payment method you used for the purchase.
Authenticity & Condition of the Watches
I guarantee you that all watches I offer are exclusively new original products. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly point this out (e.g. so-called PHOTO WATCHES).
As an official dealer, I offer you exclusively authentic products. These are offered in the original packaging, with warranty card, etc., just as they are delivered by the dealer. Everything in the so-called full set. One delivers more, another less...
Warranty & Service
All watches purchased from me come with the international manufacturer's warranty, which usually lasts two years. Some brands even offer a warranty of up to 5 years.
If a warranty case occurs, I will take care of the shipping to the manufacturer or the responsible service center for you and also organize the return shipment to you. In addition, I handle all communication with the manufacturer so that you don't have to worry about anything.
Even after the warranty period has expired, I remain your contact person and support you with service questions or repairs.
No response received?
You wrote to me via the contact form, through the price proposal, directly by email, chat, but you haven't received a reply?
Then please check your SPAM folder! Many providers are getting crazier and pushing more and more into spam.
I usually answer every inquiry within 24 hours at the latest. On weekends, it can sometimes take a bit longer. As a rule, I respond within a few minutes or hours.
Something can slip past me sometimes too. Or the technology doesn't work as it should. Feel free to write to me again at david@watchdavid.com
Mechanics - Sometimes things can happen there too
Before I ship your order, I carefully check each watch for visible defects.
If a problem should occur, such as damage during transport, please inform me immediately. I will do everything possible to quickly find a solution and ensure that you are satisfied.
My goal is to offer you not only high-quality products but also a first-class shopping experience. I look forward to welcoming you as a satisfied customer!
