Bomberg BOLT-68 User Manual page 5

What can I do to ensure that my watch functions perfectly for many years?
Magnetic fields: avoid putting your watch on a loud-speaker or a refrige-
rator because these machines create magnetic fields that may damage it.
Salt-Water: always rinse your watch in fresh water after swimming in the sea.
Shocks: avoid subjecting your watch to shocks, including sudden changes
in temperatures.
Screwed crown: always make sure you have screwed the crown properly to
avoid any humidity getting into the mechanism.
Cleaning: use a toothbrush and soapy water to clean bracelet and water
resistancy cases and a soft cloth to dry off afterwards.
avoid all direct contact with solvents detergents,
Chemical products:
perfume, cosmetics, etc. which may damage the bracelet or strap, the
case or the gaskets .
Temperatures: avoid exposing your watch to extreme temperatures (over
60°C or 140°F and under 0°C or 32°F) and to sudden fluctuations in tem-
perature.

Water-resistance: we cannot guarantee that your watch will be permanently
water-resistant. The gaskets may be affected by wear or by an accidental
shock to the crown. As recommended in our service instructions, you
should have the water resitancy gaskets of your watch tested once a year
by an approved Bomberg agent.
Chronograph pushers: do not adjust the pushers under water as this
could cause wetness in the mechanism.
