INTRODUCTION

Special recommendationS

What must I do to ensure that my OMEGA watch provides me with excellent service for many years?
Magnetic elds : avoid placing your watch on computers, loudspeakers or refrigerators, since they

generate powerful magnetic elds.

Swimming in the sea : always rinse your watch with fresh water afterwards.
Shocks : whether physical, thermal or other, avoid them.
Crown : push it back against the case into the wearing position to prevent moisture from entering the

case.
Cleaning : for metal bracelets, rubber straps and water-resistant cases, use a toothbrush and soapy

water for cleaning and dry with a soft cloth.
Chemical products : avoid direct contact with solvents, detergents, perfumes, cosmetics etc., since

they may damage the bracelet, case or gaskets.
Temperature : avoid exposure to extreme temperatures (greater than 60°C, or 140°F, less than 0°C, or

32°F) or extreme temperature changes.
Water-resistance : a watch’s water-resistance cannot be permanently guaranteed. It may notably be

affected by the ageing of gaskets or by an accidental shock to the crown. As stipulated in our service
instructions, we recommend you have the water resistance of your watch checked once a year by an
authorised OMEGA Service Centre.

Chronograph push-pieces : do not operate chronograph pushers under water in order to prevent water
entering the mechanism.

English

What are the service intervals ?

Like any precision instrument, a watch needs regular servicing to ensure that it functions perfectly. We
cannot indicate the frequency of such work, since it depends entirely on the model, the climate and the
owner's individual care of the watch. As a general rule, a watch should be serviced every 4 to 5 years,
depending on the conditions in which it is used.

Who should I contact for a maintenance service or battery replacement ?

We recommend that you contact an approved OMEGA service centre or authorised OMEGA retailer.
They are equipped with the tools and apparatus required to carry out the work and the necessary
checks in a professional manner. Furthermore, these entities can guarantee that their work is carried out
in accordance with OMEGA's strict quality standards.

A worn-out battery should be replaced immediately in order to reduce the risk of leakage and

consequent damage to the movement. The type of battery is dened on the guarantee card enclosed

with your watch.

EXAMPLE 1 trip planninG

The functions of the SPEEDMASTER SKYWALKER X-33 watch can be useful in a host of situations in

everyday life, at the ofce, in sport or travel.

Let's take the case of planning a trip from Zurich to New York for the Christmas holidays.

With take-off scheduled at 9:50 from Zurich, and landing at 12:35 in New York on 21 December, you

should program a wake-up time using an alarm, and the check-in time using a PET function (in order to

nd out the time remaining until the check-in deadline).

Since the main deadline of the "mission" is take-off from Zurich, the MET function will be programmed
to this time. The landing phase will be programmed according to New York time.

Setting the time zones:

: Zurich time = +1 hour (see page 14)14))

: New York time = -5 hours (see page 14)14))

Programming:

: reference at 9:50 on 21.12.2014 (see page 1�)1�))
: reference -2 hours (relative programming, see page 20)20))

EXAMPLE 2 Space miSSion

The SPEEDMASTER SKYWALKER X-33 watch was specially designed in collaboration with the
European Space Agency (ESA) to enable astronauts to manage the various stages of their missions.

The one described below represents a specic application scenario for which this watch was designed.

The mission consists of executing the following points:

• take-off from Kourou on an Ariane M rocket designed for lunar missions;

• establishing terrestrial orbit;

• injection into lunar transfer;

• establishing lunar orbit;

• separation of the descent and landing module;

• moon walk outside of the module in full-pressure suit;

• take-off to meet up with the return module waiting in lunar orbit;

• approach and docking to the return module;

• injection into terrestrial transfer;

• atmospheric entry off Kourou.

31

English

EXAMPLE 2 definition of fUnctionS

Setting the time zones:

: reference time zone.

: Kourou time zone, French Guiana = UTC -3.

: Cologne time zone => UTC +2 (astronaut's family home).

Programmable functions:

: rocket take-off time. This function will be dened as a favourite, and monitored by the

astronaut throughout the mission.

: booster ignition time for establishing terrestrial orbit. Certain stages prior to transfer booster

ignition must be executed with precision, and will be monitored with .

: booster ignition time for lunar transfer. Certain stages prior to booster ignition must be executed

with precision, and will be monitored with .

: daily wake-ups during the mission preparation quarantine phase.

: astronaut wake-up in orbit around the Earth on the rst morning.

This example describes only the functions as far as lunar transfer propulsion, with the parameters

below specific to the rocket trajectory during propulsion.
