by this watch should be considered as reasonable representations only.
• The Moon phase indicator and tide graph data that appear on the display of this
watch are not intended for navigation purposes. Always use proper instruments
and resources to obtain data for navigation purposes.
• This watch is not an instrument for calculating low tide and high tide times. The
tide graph of this watch is intended to provide a reasonable approximation of
tidal movements only.

Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is
stored by a rechargeable battery. Leaving or using the
watch where it is not exposed to light causes the battery
to run down. Make sure the watch is exposed to light as
much as possible.
• When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced significantly if
the face is covered only partially.

functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.
