OMEGA Speedmaster X-33 Marstimer: Built for Earth and Beyond

OMEGA Speedmaster X-33 Marstimer

Every generation of the OMEGA Speedmaster has pushed the boundaries of what a professional watch can do. The X-33 Marstimer continues that legacy, not by looking back at the Moon, but by preparing for Mars.

Developed in collaboration with the European Space Agency (ESA), this watch isn’t a marketing exercise. It’s a purpose-built instrument designed to operate both on Earth and on the Red Planet. The Speedmaster lineage has always been defined by function over form. The Marstimer keeps that spirit alive, while pushing mechanical and digital technology into new territory.

ENGINEERED FOR TWO WORLDS

At its core is the OMEGA Calibre 5622, a thermo-compensated quartz movement created specifically for the unique timing demands of space exploration. It’s precise, stable, and able to handle calculations no mechanical watch could attempt.

The watch provides a range of specialised functions including Mars Coordinated Time (MTC), multiple Martian time zones, Mission Elapsed Time (MET), Phase Elapsed Time (PET), alarms, and a perpetual calendar. It even incorporates a solar compass that works on both planets, allowing the wearer to find true north on Earth or Mars.

Everything about this watch has been designed with a clear purpose. It isn’t about novelty; it’s about capability.

DESIGN THAT TELLS A STORY

The X-33 Marstimer measures 45 mm in diameter, crafted from grade 2 titanium to keep the weight down while maintaining strength. On the wrist, it feels substantial but never heavy. The matte surfaces and satin finishing reflect its professional origins. This is a tool, not a trophy.

The bezel is made from oxalic-anodised aluminium in a rich red-hematite tone, echoing the distinctive colour of the Martian surface. The black dial is punctuated with bright white hands and indices, while the seconds hand transitions from black to red-hematite in a subtle nod to the planet it’s built to track.

The hybrid analogue-digital display is clean and readable, designed for absolute clarity. All essential data can be accessed instantly via intuitive pushers positioned around the case. The sapphire crystal is treated with anti-reflective coating on both sides, ensuring legibility in harsh light or total darkness.

PRECISION WITH PURPOSE

The Marstimer is more than a chronograph, it’s a professional-grade timing system. The Calibre 5622 is not just precise; it’s intelligent. The temperature compensation ensures stable performance in extreme conditions, while the software-driven functions extend its accuracy beyond what’s possible with purely mechanical systems.

The caseback carries both the OMEGA Seahorse medallion and the ESA logo, confirming the collaboration that defines this model. Water resistance is rated at 30 metres, which is entirely fitting for a piece designed for atmospheric and extraterrestrial environments rather than the ocean.

THE EVOLUTION OF A LEGEND

The Marstimer sits within the lineage of the Speedmaster Professional, the only watch certified by NASA for spaceflight and extravehicular activity. Where the Moonwatch marked humanity’s first steps beyond Earth, the X-33 Marstimer looks forward to the next horizon.

It represents Omega’s ongoing partnership with international space agencies and its commitment to functional innovation. It’s not nostalgia. It’s progression.

THE COMPLETE PACKAGE

The watch is supplied with a grade 2 titanium bracelet and an additional matching NATO strap presented in a dedicated roll. Each set includes the tools required for strap changes and comes with a full five-year OMEGA warranty.
