Home Site Data

Moon phase, Moon age data, tide graph data, and World Time Mode times will not be displayed properly unless Home Site data (GMT differential, longitude, and lunitidal interval) is configured correctly.

• The GMT differential is the time difference of the time zone where the site is located from Greenwich Mean Time.

• The lunitidal interval is the time elapsing between the Moon’s transit over the meridian and the next high tide. See “Lunitidal Interval” for more information.

• This watch displays lunitidal intervals in terms of hours and minutes.

• The “Site Data List” and “Lunitidal Interval List” at the back of this manual

provide GMT differential, longitude, and lunitidal interval information around the world.
