Your Tide Watch
Your Wenger Tide Watch is accurate for the Atlantic Ocean tides only. It will not
accurately track tides for other oceans.
Your Wenger Tide Watch is capable of tracking tides in two locations, a home
(primary) and a destination (secondary) port, as an example.
The Tide Indicator hand (see page 3) tracks the progress of the Tide for both the
primary and secondary tides. It will make one revolution approximately every
12 hours and 25 minutes (the approximate time between the two high tides
and two low tides each day).
The progress of the tide for your primary location can be read on the Primary
Tide Indicator (the inner ring closest to the center of the watch dial), with High
Tide at the 12:00 position and Low Tide at the 6:00 position. The progress of the
tide for your secondary location can be read on the Bezel/Secondary Tide
Indicator (the rotatable outer ring of the watch).

Important Note: Your Wenger Tide watch should be used for recreational
purposes only. It is not intended to be a navigational tool.
About Tides
Your Wenger Tide watch measures lunar tides which are created by the attrac-
tion of the Earth and the moon. The moon pulls at water causing oceans to con-
stantly move. As the moon travels around the earth and they travel around the
sun, the combined gravitational forces cause the world’s oceans to rise and fall.
The Earth makes one full axis revolution every 24 hours yet it takes the Moon
29 days to make one revolution around The Earth. As a result, it takes approxi-
mately 24 hours and 50 minutes for the moon to align with the same location
on Earth.
Approximately twice a day, powered by the moon’s attraction, the oceans swell
toward coastlines, reach their crest, and then begin to recede once more. These
ebbs and flows cause two High and two Low tides approximately every day.
For more information on Tides, we suggest researching the internet.
