GMT-24h
Acknowledgements
Thank you for choosing a watch from TISSOT
®
, a Swiss brand based in Le Locle since 1853. Meticulously designed, using only the highest quality materials
and components, your watch is protected against impacts, temperature variations, water and dust.
Your GMT-24h watch has both a traditional local time display and a 24h display, enabling you to follow another time zone.
To ensure that your watch operates with perfect precision for many years to come, we advise you to pay careful attention to the advice given in this user
manual.

Setting the GMT display (2

time zone)
Pull the crown out to position III; the seconds hand will stop. Turn the crown forward or backward to simultaneously
set the GMT display (2
nd
time zone) and the minute hand. Do not worry about setting the hour hand (local time) or the
date at this stage. Push the crown back into position I. The seconds hand will start running again. The GMT display and
minute hand are set.

Setting the local time and the date
Pull the crown out into position II. The seconds hand will continue to run. The hour hand will make one-hour jumps
forward, and the date will change whenever the hour hand passes midnight. When the date is set, continue turning the

Winding automatic mechanical watches
Your TISSOT
®
watch must be wound manually if it has stopped or not been worn for several days, in order to ensure that
your watch remains in continuous operation during periods of low activity (e.g. during sleep).
In these cases, put the crown into position I, and turn it through approximately 30 revolutions forward. The automatic
winding system then ensures that the movement is fully wound if the watch is on your wrist. It is also possible to
fully wind your watch manually by means of the winding crown. However, please note that automatic movements
have a slipping spring, which disengages the winding system (the crown can be turned infinitely) once the movement
has been fully wound. Generally speaking, 55 revolutions of the crown are enough to fully your TISSOT
®
watch.
The efficiency of the automatic winding system of a mechanical movement depends on the wrist movements of the person wearing the watch.
Do not deliberately shake your automatic watch to wind it; this has no effect and could damage the watch.
GMT function
Traditionally, the term GMT is used to designate Greenwich Mean Time.
This reference time was used for much of the 20
th
Century, before being replaced by the more precise Coordinated Universal Time (UTC), in 1972.
In the world of watchmaking, the acronym GMT is used when a watch has a second time zone display on its dial; you can choose the one you want.
