General advice
to preserve the water resistance for as long as possible, the watch should
be rinsed whenever it has been in contact with seawater, chemicals, etc.
If your watch is frequently worn in water or underwater, we recommend
having its water resistance checked at yearly intervals.
the watch is designed to withstand high levels of mechanical wear and
tear and is shock resistant as per dIn 8308. nevertheless, it goes without
saying that continual mechanical stress in the form of impacts or vibration
will affect its durability.
Care should therefore be taken to protect your watch from unnecessary
wear and tear. It is only possible to judge how well the watch keeps time
after it has been in operation for approximately eight weeks, since it takes
that long for the working mechanism to become adjusted, especially in
view of the fact that everybody has different lifestyles and habits. In the
event of any excessive deviation, please keep a day-to-day record of its
timekeeping over a period of about one week, for example.
Do you have any questions?
our employees will be pleased to advise you.
