The Speedmaster X-33 Marstimer was specially designed in collaboration with the European Space
Agency (ESA) for managing and following missions to Mars.
The various functions will enable you to follow the stages of such a mission, from take-off to landing on
Mars, and tell you the local time at the rover's location on Mars, as well as the number of sols(1) elapsed
since landing. With the Speedmaster X-33 Marstimer, you can also use the functions in everyday life to
manage the stages of a project or trip, for example.
The Speedmaster X-33 Marstimer is manufactured under licence from the European Space Agency
(ESA), and is protected by the patent below:
• Title ELECTRONIC WATCH FOR SPACE AND/OR SURFACE EXPLORATION
• Application no. PCT/EP2020/061140
• Publicationno.  WO2021/213640A1
The European Space Agency (ESA) is an intergovernmental organisation, and as such, is not
involved in the manufacture and/or marketing of the Speedmaster X-33 Marstimer.
(1) A sol is a Martian day, which lasts 24 hours, 39 minutes and 35.244 seconds.

INTRODUCTION SPECIAL RECOMMENDATIONS
What do I need to do to make sure that my OMEGA watch will work perfectly for many years to come?
Magneticelds:avoid placing your watch on a magnet, speaker, refrigerator or electronic
tablet case, since they can generate powerful magnetic elds that can disrupt your
timepiece.
Bathing in the sea: always rinse your watch in fresh water afterwards.
Impacts: avoid exposing your watch to mechanical or any other impacts, as well as thermal
shocks.
Crown: push the crown back into the neutral position to prevent water from penetrating the
mechanism.
Cleaning: for metal bracelets, rubber straps and water-resistant cases, use a toothbrush
and soapy water for cleaning, and a soft cloth for drying.
Chemicals: avoid direct contact with solvents, detergents, perfumes, cosmetics, mosquito
repellents, etc., since they can damage the wristlet, case or gaskets.

5
Temperatures: avoid exposing your watch to extreme temperatures (higher than 60°C or
140°F and lower than 0°C or 32°F), or to extreme variations.
Water resistance: the absolute water resistance of a watch cannot be guaranteed forever.
In particular, it can be affected by ageing of the gaskets, or by an accidental impact on the
crown. As stipulated in our service instructions, we recommend having your watch's water
resistance tested once a year by an approved OMEGA service centre.
Pushers: do not operate the pushers underwater, to prevent water from penetrating the
mechanism.
Different strap sizes: For leather, rubber and fabric straps, there are various sizes available
from your OMEGA point of sale, other approved points of sale, or from omegawatches.com.
Bracelet length adjustment: you can visit an OMEGA point of sale or approved service
centre to have the bracelet length adjusted to your wrist. The specialists will measure your
wrist circumference, and provide guidance to optimise the wearing comfort of your watch.
What are the intervals between services?
Like any precision instrument, a watch requires regular servicing to ensure it operates
perfectly. We cannot specify the frequency of this operation, since it is entirely dependent
on the model, climate and care that each owner takes with their watch. As a general rule,
a watch should be serviced every 5 to 8 years, according to the conditions under which it
is used.

English
Who should I contact for any battery service or replacement operation?
We recommend contacting an approved OMEGA service centre or an authorised OMEGA
dealer. They will have the tools and equipment required to undertake this work, and perform
the necessary checks in a professional manner. In addition, these specialists can guarantee
that their work will comply with the strict quality standards applied and stipulated by
OMEGA.
A drained battery must be replaced as quickly as possible, to prevent the risk of leakages,
which can damage the movement. The battery type is stated on the warranty card
accompanying your watch.
