Supernova Millennium Ralf Tech X CNES Aviator Watch
In a watchmaking landscape where innovation is sometimes subtle, Ralf Tech is making a bold statement in 2026 with a new creation resulting from its collaboration with CNES (the French National Centre for Space Studies). Named the WRX Electric Supernova Millennium, this timepiece embodies a technical, scientific, and symbolic approach, exploring the concept of time through two extreme environments: the ocean depths and the vastness of space. It is available in a limited edition of 100 pieces at a retail price of €4,800.
An aviator's watch inspired by extremes
The Supernova Millennium is more than just a robust timepiece: it tells a story. It's the story of time expanding in the abyss, where pressure and darkness alter perception, and accelerating in space, particularly during the stellar explosions known as supernovas. This parallel between two opposing universes, linked by the fundamental laws of physics, forms the conceptual foundation of this watch. It conveys a powerful idea: time is not absolute, but depends on its environment.
A streamlined design without compromise
Visually, the watch retains the DNA of the WRX collection, while evolving towards greater technical sophistication. The Grade 1 titanium case, used in the aerospace industry, has been redesigned to drastically reduce its weight. The result: a weight saving of over 100 grams, without altering the dimensions or the robustness of the structure. This optimization illustrates a modern approach to instrumental watchmaking: lightening without compromising.
A dial inspired by space cockpits
The dial adopts a radical philosophy: eliminating the superfluous. Inspired by piloting interfaces, particularly those of the International Space Station, it prioritizes immediate legibility. Its aesthetic directly evokes space: constellations, nebulae, and stellar phenomena are subtly depicted. This graphic choice reinforces the immersive dimension of the watch, designed as a true exploration tool.
A hybrid movement with exceptional battery life
At the heart of the Supernova Millenium lies the RTE001 caliber, developed specifically for Ralf Tech. This movement is based on micro-hybridization technology aimed at reducing moving components and optimizing energy consumption. Powered by a high-capacity lithium battery, the watch boasts an impressive battery life of up to 100,000 hours, or nearly 12 years. A rare performance that pushes the boundaries of industry standards.
An aviator's watch designed for extreme conditions
The Supernova Millennium's instrumental nature is confirmed by its technical specifications. It is designed to withstand particularly harsh conditions:
- Extreme temperatures from -120°C to +65°C
- Resistance to vibrations and accelerations up to 8G
- Certified water resistance to 1000 meters
These performance characteristics were notably validated during microgravity tests conducted in 2024, highlighting the watch's near-space-ready capabilities.
An exclusive sealing system
One of the most remarkable technical features is its encapsulated case back. This proprietary system guarantees lasting water resistance, while requiring specific tools for any intervention. This approach ensures that each maintenance service preserves the original performance, with servicing recommended only every 10 to 12 years.

In short, the Ralf Tech X CNES Supernova Millenium pilot's watch
With this new creation, Ralf Tech offers not just a timepiece, but a vision. A vision of watchmaking geared towards exploration, where technology and scientific artistry converge. The WRX Electric Supernova Millenium thus stands out as an object straddling the line between professional instrument and aesthetic statement, designed for those who see time as a dimension to be explored, not simply measured.
