A watch that celebrates the planet Mars: the RED 3,721
Each mission, each image sent back by a probe, each grain of dust analyzed brings us closer to a more refined understanding. Science progresses step by step, with the rigor and patience that characterize it.
Just recently, researchers published results in the journal Nature suggesting the possibility that ancient traces of life may have existed on Mars. Nothing is definitive: the scientific community must, as always, compare, debate, and verify. But each discovery adds a page to this "Martian book" that humanity is turning with slowness, caution, and determination. Mars remains one of the greatest challenges of knowledge: an enigma whose answer requires the collective effort of entire generations.

It is this scientific and human adventure that Col&McArthur has chosen to celebrate with the Red 3,721: a watch that pays homage to the planet Mars , translating into a unique horological object the devotion, rigor and patience that shape our understanding of the universe day after day.
The Red 3721 watch: the planet Mars on your wrist… for real
The name of the Red 3.721 space watch evokes Martian gravity (3.721 m/s²). Behind this number lies the very spirit of our approach: to unite scientific rigor with the drive of dreams.
We wanted the dial of this watch, featuring the image of the planet Mars, to be more than just a decoration. Sculpted in 3D relief, it faithfully reproduces the Martian surface as revealed by our mapping missions, from the Mars Global Surveyor to the Mars Reconnaissance Orbiter. Every hollow, every irregularity invites you to contemplate Mars differently, not as a distant abstraction, but as a very real Earth, shaped by time.
- The exact coordinates of Jezero crater, where the Perseverance rover landed on February 18, 2021.
- The mention "Perseverance" is a tribute to this instrument of science and determination.
- The landing date recorded at noon, a precise record of an accomplished feat.
- A binary code that encodes "March 02/18/21", a secret engraved for those who know how to read it.

At three o'clock, a sealed chamber contains genuine Martian dust (NWA 14269), certified by independent specialized laboratories. This tangible detail, which was very important to us, is not merely decorative: it establishes the most concrete link possible between the watch and the planet Mars . Wearing the RED 3,721 watch means keeping a sample of the Red Planet close at hand.
The case back features the official NASA logo, a testament to our official collaboration with NASA for our horological tribute to the planet Mars currently being explored.
A collective horological tribute to the planet Mars and to science
The epic journey to Mars through the ages is, above all, a human adventure. Thousands of engineers, researchers, astrophysicists, and technicians work together to make every observation, survey, and subsequent mission possible. The success of Perseverance is not the work of a single mind, but the sum of collective skills and determination.
The Red 3,721 embodies this same spirit of unity. This watch, a reflection of the planet Mars, would not have seen the light of day without the trust of thousands of crowdfunding contributors, whom we thank for this shared adventure. Like Martian exploration, the birth of this exceptional timepiece is a story of patience, dedication, and shared determination. It embodies the conviction that the greatest achievements blossom from collective effort.
