RALF TECH WRX Electric Space Millenium x CNES Titanium 47mm
RALF TECH built its reputation looking towards the depths. With the Space Millenium, it looked in the opposite direction.
Created in collaboration with CNES, the French National Centre for Space Studies, the WRX Electric Space Millenium represents the meeting of two extreme environments: the abyss below us and the space beyond.
More importantly, this is not simply a WRX decorated with a space-agency logo.
The familiar 47.5mm WRX architecture has been comprehensively reworked in Grade 1 T35 aerospace titanium, with an open, organic case construction designed specifically to reduce mass. The result weighs just 95 grams — approximately 105 grams less than a conventional WRX.
At its centre sits an equally unusual black composite honeycomb dial, developed both for lightness and exceptional legibility. Enlarged C5 Super-LumiNova® indices stand prominently against the structure, while the CNES signature at six o'clock quietly identifies the collaboration.
The engineering remains unmistakably RALF TECH.
A huge 5.9mm curved sapphire crystal, protected screw-down crown and exclusive encapsulated caseback contribute to a genuine 1,000 metres / 3,300 feet of water resistance. RALF TECH states that the watch operates across temperatures from -50°C to +55°C, with production models subjected to zero-gravity testing in March 2024.
Inside is the RTE001 Long Range Electric Micro Hybrid movement, developed in Switzerland for RALF TECH, offering extraordinary autonomy of up to 100,000 hours — almost twelve years.
The specially developed CNES ballistic-nylon strap uses a hook-and-loop adjustment system allowing the watch to be worn conventionally or over a flight suit.
Only 100 pieces will be produced.
Why buy it?
Because very few watches genuinely connect two worlds this convincingly.
The WRX was born from diving and extreme underwater environments. Here, its fundamental architecture has been re-engineered for an entirely different frontier.
Titanium replaces steel. Weight becomes critical. A composite honeycomb dial replaces convention. And nearly twelve years of autonomy suddenly begins to make rather more sense when the objective is reliability somewhere far beyond the nearest watchmaker.
There is also something wonderfully eccentric about owning a watch capable of surviving 1,000 metres beneath the ocean while being developed with the French space agency for conditions above the atmosphere.
From the abyss to the stars — perhaps the most unexpected journey the WRX has ever taken.
