Bremont sends its supernova chronograph to the moon’s surface

At a glance:

• Bremont’s 41 mm Supernova Chronograph will ride Astrolab’s FLIP rover to the lunar south pole in 2024‑25.
• The watch is a 904L stainless‑steel, automatic chronograph with a 62‑hour power reserve and a blue‑emission Super‑LumiNova dial.
• The mission is part of Astrobotic’s Griffin‑1 payload, a one‑way rover that will test dust‑mitigation wheels and survive a two‑week lunar night.

What happened

Bremont, the British luxury watchmaker now owned by Wall Street investor Bill Ackman, announced that its newest piece – the Supernova Chronograph – will be attached to the chassis of the Flex Lunar Innovation Platform (FLIP), a lunar rover built by California‑based aerospace startup Astrolab. The rover is slated to launch as part of Astrobotic’s Griffin Mission One (Griffin‑1) and is expected to land at the Moon’s south pole sometime in the second half of this year. Unlike the traditional astronaut‑issued Omega Speedmaster X‑33 on Artemis II, Bremont’s watch will not be worn by a crew; instead it will sit vertically in a specially‑designed housing between the rover’s front wheels, its face visible to FLIP’s high‑definition cameras.

The Supernova Chronograph is a 41‑mm integrated‑bracelet sports chronograph crafted from 904L stainless steel. Its three‑dimensional perforated dial draws visual cues from spacecraft solar sails, featuring an interlocking grid over a full‑layer of blue‑emission Super‑LumiNova that glows “like the energy inside spaceships, or light‑speed acceleration in Star Wars,” according to Bremont CEO Davide Cerrato. The watch houses a Sellita‑made automatic chronograph movement, rated as a chronometer, with a 62‑hour power reserve and a decahedral black ceramic bezel.

The supernova chronograph in detail

Bremont describes the Supernova as the inaugural reference of a new, explicitly futuristic space‑inspired collection. Its case construction reworks the brand’s signature Trip‑Tick architecture into a sandwich‑style three‑piece layout, while a multifaceted black ceramic bezel adds durability for the harsh lunar environment. Weighing 107 grams, the watch head will be glued into place with a specialist composite, ensuring it remains visible but immobile during the rover’s long lunar night.

Because the mechanical movement relies on the wearer’s arm motion to wind the rotor, the watch will stop once its 62‑hour reserve is exhausted during the two‑week lunar night. When FLIP resumes motion, the rover’s accelerations, pitches, and tilts should theoretically jolt the winding rotor back into action, albeit with less torque than on Earth. “My guess is that the watch will function from time to time, but for short periods,” Cerrato said, noting the experiment is as much about inspiration as it is about precision timekeeping.

Astrolab’s FLIP rover and its mission profile

FLIP weighs 1,058 pounds and carries a mix of commercial and government payloads, four HD cameras, and a deployable solar array. It serves as a technology demonstrator for Flexible Logistics and Exploration (FLEX), Astrolab’s larger SUV‑sized rover concept intended to support NASA’s Artemis program. Developed from a blank sheet after NASA’s VIPER vehicle was paused in 2024, FLIP was built in roughly a year after Astrolab secured the contract in late 2024.

The rover’s standout feature is its hyper‑deformable wheels, composed of silicone, composite, and stainless steel. These wheels create a soft, enlarged contact surface that mimics deflating a Jeep tire for off‑road traction, allowing FLIP to traverse the Moon’s regolith without sinking. The wheels are designed to survive the lunar night’s extreme cold—around –200 °C (–328 °F)—which would shatter conventional rubber tires.

Testing regime for watch and rover

Both the Supernova Chronograph and the FLIP rover are undergoing Spacecraft Protoflight Qualification testing at Astrolab’s Hawthorne, California facility. The regimen includes bake‑out cycles to drive off volatiles, thermal cycling between extreme temperatures, and thermal‑vacuum cycling inside a vacuum chamber. Electromagnetic interference testing is also performed.

Mechanical stresses are simulated on shaker tables that replicate launch‑vehicle vibration profiles, followed by random vibration, shock testing with hammer impacts to emulate stage separations, and acoustic testing in a high‑decibel chamber. Bremont’s own heritage of aircraft‑ejector‑seat testing gives the brand confidence, though Cerrato admits the numbers for temperature, aging, vibration, and radiation exposure are “far more extreme than what it will experience during the mission.”

Industry reaction and parallel developments

Bremont will not be alone in courting lunar prestige. Yesterday Breitling unveiled a limited‑edition Navitimer Cosmonaute Artemis II with a blue meteorite dial, while today IWC Schaffhausen introduced the Pilot’s Venturer Vertical Drive, a tool watch engineered from the ground up for human spaceflight in partnership with Vast’s Haven‑1 commercial space station. Meanwhile, California startup Barrelhand has been developing the Monolith, an EVA‑rated mechanical tool watch with a 3D‑printed titanium chassis and a fully ceramic dial built to survive ultraviolet radiation and temperature swings.

These concurrent announcements highlight a broader trend: luxury and technical watchmakers are turning the Moon into a new branding frontier. By the end of 2026 the White House has tasked NASA with coordinating a new atomic‑clock‑based standard, Coordinated Lunar Time, to underpin navigation and communication beyond Earth. While a mechanical chronograph on a rover chassis will have negligible impact on that standard, the symbolic value of a timepiece physically present on the Moon cannot be overstated.

Looking ahead

If the Supernova Chronograph survives the lunar night and resumes operation when FLIP moves again, it will become the first Bremont—and possibly the first British—watch to have set foot on another celestial body. The mission is a one‑way deployment; the rover will remain permanently on the lunar surface, continuing to gather dust‑accumulation data and test coating technologies. For Bremont, the venture is as much a marketing coup as a technical experiment, promising to “project us into a thinking process that is absolutely out of the box,” according to Cerrato.

Future lunar missions, both governmental and commercial, will likely carry more specialized instrumentation, but the presence of a luxury chronograph underscores how space exploration is permeating popular culture and high‑end consumer markets alike. As humanity prepares for a sustained presence on the Moon, the tick of a mechanical watch may become an unexpected metronome for a new era of lunar timekeeping.
