Magnetic fields
Whenever possible keep your watch away from mag-
netic fields like speakers, electric devices, security gates
at airports or other electromagnetic appliances. Such
devices produce strong magnetic fields that may affect
the functions of your watch, influence the accuracy of
time keeping or even completely stop it.
Temperatures and shocks
HAMILTON recommends not to expose your watch
to extreme climatic changes (exposure to sunlight
followed by immersion in cold water) or extreme tem-
peratures over 60°C (140°F) or under than 0°C (32°F).
HAMILTON recommends not to wear your watch for
sports like golf, tennis or similar activities which cause
heavy shocks because they could damage the micro-
mechanical parts in the movement.
Batteries
Watch batteries can last from between two and five
years, depending on the movement type and the
amount of energy used by the various functions. If the
second hand begins to jump in 4 second intervals, the
battery needs to be changed (end of life indicator).
We recommend that you take your watch to an autho-
rized HAMILTON Service Center or official HAMILTON
retailer as they have the necessary tools and testing
equipment to carry out the work professionally and
based on the HAMILTON standards.
An empty battery must be changed as soon as possible
to avoid the risk of leakage and resulting damage to the
watch mechanism.

Manual winding
The most traditional of movements in watch-
making is the manually wound one. To ensure
that the watch does not stop, it must be wound
regularly – once a day.
Automatic
The mechanism of the watch includes an oscil-
lating rotor that winds the mainspring via the
motion of your wrist. If necessary, the watch
may be rewound manually.
