Omega X-33 Marstimer Leaves the Catalogue: The Tool Watch That Still Has a Job

The Omega Speedmaster X-33 Marstimer has left the brand’s consumer catalogue, following the earlier disappearance of the Skywalker. That removes the digital Speedmaster from the public collection, but it does not make the X-33 irrelevant. If anything, the exit clarifies what the watch always was: a professional instrument sold to enthusiasts, rather than a conventional luxury chronograph with an LCD added for theatre.
For collectors, the important question is not whether catalogue removal creates instant scarcity. It is whether the Marstimer’s unusually specific functions, short retail life and service requirements make sense as a long-term ownership proposition.
A retail exit is not the end of the job
The X-33 family has always occupied two worlds. Consumer references were sold through Omega boutiques, while agency work followed operational requirements. A missing retail listing therefore does not prove that every institutional X-33 has stopped being supplied. It only confirms that a private buyer can no longer select a new Marstimer or Skywalker from the standard catalogue.
That distinction should temper speculation about a fourth-generation successor. A new X-33 may arrive; there is no announced replacement to evaluate today. Buying the existing reference purely because a hypothetical Gen 4 might appear is backwards. The current watch has to justify itself on its own functions, ergonomics and condition.
Mars time is useful on Earth
Introduced in 2022, reference 318.90.45.79.01.003 uses Omega’s thermo-compensated quartz calibre 5622 inside a 45mm grade-2 titanium case. Its Mars Time Coordinated function tracks a sol, roughly 39 minutes and 35 seconds longer than an Earth day. The solar compass can find true north on either planet, while Mission Elapsed Time, Phase Elapsed Time, alarms, countdown timing, UTC and a perpetual calendar carry over the X-33’s practical logic.
The Mars functions were developed for mission teams on Earth, including work connected with rover operations. That matters because it prevents the watch becoming a costume prop. The display is specialised, yet the use case is real: coordinating events across a non-terrestrial day without converting every timestamp by hand.
Readability is the genuine compromise
The analogue hands preserve an immediate time reading, while the digital screen carries the denser information. The negative LCD looks coherent with the black dial, but it is not as effortless as a positive display in poor light. Prospective owners should test every mode, the backlight, all pushers, the crown and the alarm rather than admiring only a static dial photograph.
Water resistance is 30 metres, modest for a modern titanium sports watch. The reason to accept that limit is the audible alarm architecture, not aquatic versatility. A buyer who wants one watch for swimming and travel should be honest about the mismatch.
Completeness and service now matter more
Catalogue exit moves the buying process toward existing dealer stock and pre-owned examples, where completeness becomes material. The original package included the grade-2 and grade-5 titanium bracelet, dedicated NATO strap, strap-changing tool and a roll lined with a reproduction of Hebes Chasma. Missing accessories do not make the watch unusable, but they change the collecting proposition and should affect the asking price.
Ask for battery and service records, confirm that the display has no missing segments, and test alarm volume before purchase. Inspect the bracelet screws, clasp, bezel insert and pusher action. The caseback should carry the Marstimer and “ESA tested and qualified” markings appropriate to the reference.
Historical launch figures also need careful labels. Contemporary reports placed the watch at CHF 5,900 before tax, about €7,100 including tax, and US$6,400. Those are 2022 launch prices, not evidence of current retail availability or completed secondary-market sales.
The collector case
The strongest reason to own a Marstimer is not that it vanished from a website. It is that few luxury watches were designed around a genuinely different time standard and then tested for an agency-defined task. The weakest reason is the hope that discontinuation alone will force prices higher.
Buy the X-33 if its display, alarms and mission timers are functions you will learn, and if a 45mm ana-digital instrument belongs in your collection. Otherwise, the catalogue exit changes little. Rarity without use remains only a story; the Marstimer is more convincing when treated as a tool.
