RALF TECH WRX: a watch born in the field

To understand the WRX, one must first understand RALF TECH’s DNA. The brand was founded by Frank Huyghe, a professional diver and watch enthusiast, in a world far removed from traditional luxury: technical diving, professional equipment and extreme environments. Before becoming a recognised watch brand, RALF TECH designed equipment for civilian and military divers.

The founding episode came in 2005 with the WR1, the first RALF TECH watch. It accompanied Pascal Bernabé during his world-record autonomous dive, with an immersion lasting almost ten hours and a maximum depth of 330 metres. The WRX was born from that experience: the objective was no longer simply to create a watch capable of going deep, but to create a true professional instrument, usable at sea, on land, on mission, in hostile conditions and in everyday life.

Designed in 2007, the WRX adopted an immediately recognisable architecture: a large 47.5 mm cushion-shaped case, diving bezel, very thick sapphire crystal, highly legible dial, massive construction and a tactical tool-watch spirit. A pre-series was produced in 2008, before feedback from Commando Hubert operators helped refine the final model. The WRX thus became one of the few contemporary French watches whose story is based on documented military and professional use rather than on simple aesthetic inspiration.

The key dates in RALF TECH WRX history

The WRX did not evolve like a conventional catalogue watch. Each generation responded to practical constraints: autonomy, water resistance, legibility, durability, maintenance, discretion or a dedicated series for a specific unit. Here are the main milestones to remember.

Who wore the RALF TECH WRX? Military, professional and space-related use

The WRX is one of the few modern French watches whose legitimacy comes first and foremost from its users. It is not merely a watch “inspired” by special forces: several series were developed with or for specific units.

Commando Hubert: the operational origin of the WRX

The most important link is the one between the WRX and Commando Hubert, the French Navy’s combat swimmer unit. Commando Hubert operators took part in testing and field feedback for the WRX. Their use helped improve legibility, durability, water resistance and discretion on certain versions.

The WRX A Hybrid and WRX A Hybrid O are directly connected to this world. The letter “O” refers to operators engaged in the field, with the idea of a non-reflective, legible watch capable of withstanding mission conditions.

The GIGN and intervention divers

In 2012, RALF TECH developed a WRX Hybrid II GIGN for the GIGN intervention divers. The series was reserved for members of the unit and produced in 100 pieces. This confidential dimension explains why these watches are sought after when they appear on the secondary market with clear provenance, a coherent full set or original accessories.

Special forces, elite police units and maritime professionals

Over the years, the WRX has equipped or accompanied various French and foreign units, as well as professional divers, skippers and operators facing strong operational constraints. This use by action professionals gives the WRX an image very different from that of purely lifestyle diving watches.

Thomas Pesquet, CNES and the space series

With the Space Millenium, Galaxy Millenium and Supernova Millenium series, the WRX symbolically moves from the abyss to outer space. The collaboration with CNES gave birth to limited series of 100 pieces, designed as French exploration watches. The Space Millenium has also been seen on the wrist of Thomas Pesquet, French ESA astronaut, strengthening its appeal among enthusiasts of watches connected to scientific and space missions.

To explore this universe further, Mostra has also published an article dedicated to the RALF TECH WRX Hybrid, the military watch of elite troops and professional deep divers.

WRX Automatic, Hybrid, Electric: three interpretations of the same tool watch

The WRX Automatic: the watchmaking interpretation

The automatic versions of the WRX are aimed at enthusiasts attached to traditional mechanical watchmaking. They retain the collection’s massive architecture, but with a Swiss automatic movement, a classic power reserve and a more horological pleasure. Some automatic series, such as Carbon Tech or the Night, Day and Moonlight versions, lean more towards collecting or off-catalogue models.

The WRX Hybrid: precision, autonomy and military use

The Hybrid generation is the one that firmly established the WRX as a professional watch. Its principle is to combine an electronic precision base with mechanical rotor charging. The result is a very accurate watch, more autonomous than a classic automatic and less immediately dependent on battery replacement than a traditional quartz watch.

WRX Hybrid models are now particularly interesting on the pre-owned market, especially when connected to a military series, a limited edition or a complete configuration. Commando Hubert, GIGN, Black Operator and certain professional series can generate real demand among collectors of contemporary military watches.

The WRX Electric: the modern generation

The WRX Electric marked an important evolution. It retained the original WRX design but introduced an RTE001 Long Range movement, autonomy announced at up to 100,000 hours, sandwich dials, a caseback encapsulation system and, depending on the version, water resistance from 500 to 1,000 metres.

This generation follows a very pragmatic logic: a watch that can be worn for a long time, whose autonomy far exceeds that of an automatic watch, and whose maintenance can be organised over a long cycle. For a user, this is one of the great strengths of the WRX Electric: it keeps the spirit of an instrumental watch while greatly simplifying everyday use.

The most sought-after special and military editions

Not all RALF TECH WRX watches are equal on the pre-owned market. Special series, military editions, watches linked to a unit or to an official collaboration often carry greater value in both use and collectability.

• WRX A Hybrid Commando Hubert: an emblematic model in the relationship between RALF TECH and French combat swimmers.
• WRX Hybrid II GIGN: a confidential series created for GIGN intervention divers, highly sought after when complete.
• WRX A Hybrid O: a version developed for Commando Hubert, with civilian limited series.
• WRX Black Operator: a black tactical version, strongly connected to the world of discreet professional watches.
• WRX Carbon Tech: series and unique pieces in forged carbon, very different from classic steel WRX models.
• WRX Electric Space Millenium x CNES: 100-piece limited series, titanium case, CNES collaboration, launched in 2024.
• WRX Electric Galaxy Millenium x CNES: 2025 evolution around the space universe and the Milky Way.
• WRX Electric Supernova Millenium x CNES: 2026 series limited to 100 pieces, continuing the space collaboration.
• WRX Stardust and Rockdust: contemporary limited series strengthening the collectible appeal of the Electric family.

At Mostra, pieces such as the RALF TECH WRX Electric Space Millenium x CNES, the RALF TECH WRX Electric Galaxy Millenium x CNES and the RALF TECH WRX Electric Supernova Millenium x CNES perfectly illustrate this new dimension: technical watches, but also recent collector pieces, limited and attached to an identifiable story.

The advantages of a RALF TECH WRX for its owner

Owning a RALF TECH WRX is not merely about wearing an imposing diving watch. It means wearing an instrument designed for robustness, legibility and autonomy. Its advantages are very concrete.

True tool-watch legibility

The dial is designed to be read quickly. Wide indexes, contrasted hands, Super-LumiNova, unidirectional bezel and large visual opening make it easy to read the time or elapsed time. On recent Electric versions, the sandwich dial further enhances depth and night-time legibility.

Autonomy far superior to classic mechanical watches

WRX Hybrid and Electric watches appeal to users who want a precise, always-ready timepiece. A classic automatic watch needs to be worn or wound regularly. A WRX Electric can remain ready over a very long period, with autonomy announced at up to 100,000 hours depending on the version.

A watch designed to withstand demanding use

Steel or titanium case, very thick sapphire crystal, diving bezel, screw-down crown, adapted straps and solid attachments: the WRX is designed for hard use. It can accompany an active daily life, the sea, sailing, travel, outdoor activities or professional use.

A strong wrist presence

With its 47.5 mm diameter, the WRX is not a discreet watch. It is a deliberate choice. For some wrists, it will feel too imposing; for others, that will be precisely part of its appeal. The titanium of the CNES series lightens the wearing sensation, while steel versions reinforce the impression of an instrument.

A French watch with a rare identity

In a collection often dominated by major Swiss brands, a RALF TECH WRX brings something different: an independent French brand, measured production, military links, confidential series and a radical aesthetic. It is a watch for the informed enthusiast, not for someone seeking only a familiar name.

To preserve its performance, it remains essential to have the water resistance checked regularly, especially before use at sea or after the case has been opened. You can also consult our selection of pre-owned military and air force watches to compare the WRX with other instrument watches.

Evolution of RALF TECH WRX value on the pre-owned market

The RALF TECH pre-owned market is very different from that of Rolex, Omega or Cartier. It is narrower, less speculative, but sometimes more interesting for a collector who knows the right references. The WRX should not be bought as an automatic financial investment: it should be chosen for its use, story, series and condition.

Value depends heavily on the series

Regular versions or models produced every year usually sit at more accessible levels than military or CNES series. Conversely, watches linked to Commando Hubert, the GIGN, Black Operator series, CNES editions or carbon pieces often hold higher levels, especially when complete.

Price ranges observed in 2026

As of July 2026, certain WRX Electric or Hybrid references can be observed on the market around €1,300 to €2,600 for standard or tactical models, while special, military or CNES editions often sit between €3,000 and €4,800 depending on condition, rarity and set contents. At Mostra, recent WRX Electric x CNES full-set examples are positioned around €3,950 to €4,250 depending on reference, year and configuration.

What increases value

• The full set: box, papers, card, accessories, original straps, patch or special allocation elements.
• The series: Commando Hubert, GIGN, CNES, Black Operator, Carbon Tech, numbered edition or unique piece.
• Condition: case not abused, clean bezel, intact crystal, coherent strap, no moisture inside the watch.
• Traceability: invoice, provenance, service history and coherence of the example.
• The clarity of the story: a WRX linked to a unit or identifiable collaboration is easier to resell than a watch without context.

What can limit value

• A watch without box or papers.
• Unverified water resistance.
• An undocumented intervention.
• A missing strap or accessory on a limited edition.
• Confusion between listed price, retail price and the price actually negotiated on the market.

In short, the RALF TECH WRX has a healthy pre-owned value when it is rare, complete, well maintained and properly contextualised. Its market is more confidential than that of major Swiss icons, but that is precisely what can appeal to an enthusiast of French tool watches and contemporary military series.

Buying or selling a RALF TECH WRX with Mostra: the value of expertise

Why buy a RALF TECH WRX from Mostra?

Buying a pre-owned WRX requires more than a simple price comparison. The condition of the case, the coherence of the reference, the water resistance, the original set, the presence of papers, the movement’s operation and, for military or limited editions, the coherence of the story all need to be checked.

Since 2025, Mostra has been officially recognised as a Certified RALF TECH Technical Center for pre-owned watches. This recognition is particularly important for a WRX, because Hybrid and Electric models require serious follow-up, especially regarding water resistance, gaskets, final checks and traceability.

A RALF TECH purchased from Mostra benefits from workshop inspection, a certificate of authenticity and a 3-year Mostra warranty according to the conditions stated on each product page. For a technical watch, this difference is essential: you are not just buying a reference, you are buying a verified example.

Why sell a RALF TECH WRX through Mostra?

Selling a WRX requires knowing how to explain the watch. A WRX Electric Original, a WRX Black Operator, a WRX Hybrid Commando Hubert or a WRX Space Millenium x CNES do not have the same market reading. The presence of a full set, a coherent serial number, complete accessories or service history can change the perceived value.

Through Mostra, you benefit from watchmaking expertise, market analysis and guidance in choosing the best solution: valuation, trade-in or consignment depending on the profile of your watch. You can also read our guide on selling your watch in Aix-en-Provence: valuation, trade-in and consignment sale.

Which RALF TECH WRX should you choose?

The right choice depends on your use. For a robust, legible and modern watch, the WRX Electric Original is the logical entry point. For a more tactical presence, the Black Operator and black versions offer a more radical aesthetic. For a collector sensitive to military history, the Commando Hubert, GIGN and Hybrid O series are the most interesting. For someone looking for a recent, limited French piece connected to space exploration, the Space Millenium, Galaxy Millenium and Supernova Millenium x CNES editions are particularly coherent.

In every case, Mostra’s advice is simple: choose condition, coherence and traceability first. On a niche watch like the WRX, the quality of the individual example matters as much as the reference itself.

Conclusion: the WRX, a French watch that earned its legitimacy through use

The RALF TECH WRX is a watch apart. It was not designed to follow a trend, nor to reproduce the historical codes of major Swiss dive watches. It comes from another world: professional diving, special operations, real constraints and series produced with intention.

Its story begins with the WR1 and the depth record, takes shape with Commando Hubert, expands to the GIGN and professional units, then evolves towards the Electric generation and CNES collaborations. Few contemporary French watches can claim such a clear trajectory.

For an owner, the WRX offers true utility: robustness, legibility, autonomy, water resistance and strong identity. For a collector, it offers limited, military or space-related series whose value depends on rarity, condition and traceability. For a seller, it deserves a serious valuation because its market is specific.

At Mostra, buying or selling a RALF TECH WRX means placing the watch back in its true context: a professional tool that became a collector’s object, with a story, a value and a use.
