This watch has been tested by industry standards to an
overpressure situation in a static laboratory environment.
This means the watch was not inuenced by frequent
temperature changes, saltwater, sand or big wipeouts.
Constant exposure to these situations can seriously eect
the rubber seals which keep water out.
It is recommended that every 24 month the rubber seals are
replaced and fully tested by a Billabong watch technician.
Please return to place of purchase or your closest Billabong
retail outlet.
IMPORTANT: It is not recommended to use this watch
for navigational purposes. We have compiled the most
current and accurate tide readings available at the time of
manufacture. However, weather conditions, changes in the
coastal environment and movements in the tectonic plates
can aect the tidal changes/ranges. Therefore we can not
guarantee that the information contained in this watch,
nor accept responsibility or liability for variances to actual
tide conditions.
