Each Hydrogen Watch is designed and manufactured to the
highest of standards. In order to ensure optimal performance
and longevity, please review the simple guidelines for care and
precautions of your Hydrogen Watch.
CARE
Clean your watch with water and a soft cloth only. Do not dive.

with a soft, dry cloth. It’s our recommendation that your watch be
serviced every 18-24 months to ensure longevity and
trouble-free usage.
PRECAUTIONS
It‘s important to avoid the following conditions: extreme heat or
cold, as well as prolonged periods of exposure to direct sunlight,
to wet conditions that exceed the watch water rating (see
case-back and below chart). Never operate any of the function
buttons or adjust the position of the crown when the watch is in
contact with water.
Your Watch should not be aected by magnetic fields generated
by household items such as televisions and stereos, but
avoidance of other strong electric fields or static electricity is
advised. It‘s also important to avoid extreme shock or impact.
