  • First British watch destined to live permanently on the Moon.
  • Developed with Astrolab for the FLIP lunar rover mission.
  • Spacecraft-inspired dial with full blue-emitting Super-LumiNova.
  • COSC-certified BC77AC chronograph with a 62-hour power reserve.
  • 904L stainless steel case built to withstand extreme lunar conditions

Some watch brands have built their reputation on conquering the land, sea, and sky. Bremont has decided the next frontier is much farther away. At Watches & Wonders 2026, the British watchmaker unveiled the Supernova Chronograph, the first model in an all-new collection that’s set to become the first British watch to live permanently on the Moon.

That milestone comes through a partnership with California-based aerospace company Astrolab, whose mission is to support humanity’s long-term presence beyond Earth. A Supernova Chronograph will travel aboard Astrolab’s FLIP (Flexible Logistics and Exploration Platform) lunar rover to the Moon’s south pole, where it will remain permanently instead of returning home—a remarkable achievement for both Bremont and British watchmaking.

Fortunately, you don’t need to leave Earth to own one yourself. Bremont is offering the same Supernova Chronograph to collectors, with pricing starting at USD $8,250, putting it in the conversation alongside another alternative to OMEGA’S Speedmaster Moonwatch Professional.

Here’s everything you need to know about Bremont’s most ambitious release from Watches & Wonders 2026!

Built for Life on the Moon

The Supernova Chronograph wasn’t designed to simply look like a space watch—it was engineered for the mission ahead. Because one example will spend the rest of its life on the lunar surface, Bremont had to ensure it could survive an environment far harsher than anything found on Earth. Temperatures on the Moon can swing from blistering heat in direct sunlight to near absolute zero inside permanently shadowed regions, creating one of the toughest testing grounds imaginable.

To prepare for those conditions, Bremont subjected the watch to an extensive qualification programme alongside Astrolab’s lunar rover. The Supernova underwent thermal vacuum testing, hot and cold temperature cycling, vibration and acoustic testing, electromagnetic compatibility checks, and shock simulations, with each test designed to exceed the conditions expected during launch, landing, and its permanent stay on the Moon. It’s the kind of testing more commonly associated with spacecraft than wristwatches.

Housing all of that engineering is a 41 mm case crafted from 904L stainless steel, a material chosen for its superior corrosion resistance and brighter finish compared to the more common 316L steel. The multi-part construction is paired with a DLC-coated case middle and a distinctive black ceramic decagonal bezel, giving the Supernova a modern, architectural look inspired by spacecraft engineering rather than traditional chronographs.

At 14.4 mm thick, the Supernova Chronograph certainly has presence on the wrist, but that’s hardly surprising given what it’s been built to endure. With 100 metres of water resistance, a robust integrated design, and a case engineered to survive a one-way journey to the Moon, it’s clear that Bremont prioritized capability over the pursuit of the slimmest possible profile.

A Dial Inspired by Spacecraft

If there’s one part of the Supernova Chronograph that immediately grabs your attention, it’s the dial where  Bremont’s space-inspired vision really comes to life. The three-dimensional black galvanic construction takes inspiration from the intricate geometry of spacecraft solar arrays and solar sail panels, creating a layered design that immediately sets it apart from traditional chronographs.  Underneath sits a full layer of blue-emitting Super-LumiNova, while the applied hour markers and black gold hands are filled with lume as well. You’d expect that much illumination to make the dial feel cluttered after dark, but it’s surprisingly easy to read.

The same geometric pattern continues inside the chronograph registers at 3 and 9 o’clock, tying the entire design together without making it feel repetitive. A date window at 6 o’clock and a tachymeter scale around the outer edge finish off the layout, adding useful functionality while keeping the dial clean and well-balanced. It’s a dial that manages to feel both futuristic and practical—exactly what you’d hope for from a watch that’s destined to spend the rest of its life on the Moon.

Mission Control Starts with the BC77AC

Powering the Supernova Chronograph is Bremont’s BC77AC automatic chronograph calibre, a COSC-certified chronometer built on the proven Sellita SW500 architecture. The movement features 27 jewels, beats at 28,800 vibrations per hour (4Hz), and delivers a healthy 62-hour power reserve. Bremont has also equipped it with a Glucydur balance wheel, an Anachron balance spring, and Nivaflex mainspring—components chosen for their durability, stability, and consistent timekeeping. Rather than reinventing the wheel, Bremont has refined a movement with an established reputation for reliability, a sensible choice for a watch that’s been engineered for one of the most demanding missions in modern watchmaking.

Turn the watch over, and you’ll find a decorated rotor visible through the open sapphire case back, giving owners a clear view of the BC77AC at work. The rotor’s angular design echoes the geometric styling found throughout the case and dial, creating a subtle connection between the movement and the rest of the watch. It’s a thoughtful finishing touch on the Supernova Chronograph, designed for the Moon — but also built to be enjoyed every day here on Earth.

Later this year, the Bremont Supernova Chronograph will leave Earth aboard Astrobotic’s Griffin Mission One, launching from NASA’s Kennedy Space Center in Florida. Before liftoff, the watch will be integrated directly into the chassis of Astrolab’s FLIP (Flexible Logistics and Exploration Platform) lunar rover using a specially engineered mounting plate. Once the rover reaches the Moon’s south pole, the Supernova won’t be making the journey home—it will remain on the lunar surface as part of the mission, becoming the first British watch to live permanently on the Moon.

For those of us keeping our feet firmly on Earth, Bremont is also offering the Supernova Chronograph to collectors, with prices starting at USD $8,000 on a rubber strap and USD $8,250 on the integrated 904L steel bracelet. More importantly, it’s one of the strongest releases we’ve seen from Bremont in years. The Moon mission naturally grabs the headlines, but even without it, the Supernova stands on its own as a well-executed chronograph with a distinctive identity and a story unlike anything else unveiled at Watches & Wonders 2026.
