Calibrating the High Tide Time
You obtain more accurate tide indications by the watch by calibrating its high tide time with information
you can fi nd on the Internet or in a newspaper.
• Note that the high tide time differs according to your location and the current season.
To calibrate the high tide time
1. In the Tide/Moon Mode, display the Moon Screen.
• If the Tide Screen is displayed, press

Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon appears to wax and wane
as the relative positioning of the Earth, Moon, and Sun changes. The greater the angular distance
between the Moon and the Sun,* the more we see illuminated.
* The angle to the Moon in relation to the direction at which the Sun is visible from the Earth.
See “Northern Hemisphere View or Southern Hemisphere View Moon Phase” (page E-104).
• Your watch shows the Moon phase and Moon age at noon of a date, regardless of the time displayed
by the watch.
• The Moon phase is based on the northern hemisphere view, with the Moon to the south. Note that the
Moon phase form will be reversed in the case of the southern hemisphere view (Moon to the north).
• The margin for error of the Moon age is ±1 day.
• The Tide Graph and Moon phase are displayed in the Timekeeping Mode and Tide/Moon Mode only.
• If Moon phase indication is not correct, check the Timekeeping Mode time and date settings, and the
Home City setting.

• Tide Graph readings are based on average values*.
• If the Tide Graph hand indication is not correct, check the Timekeeping Mode time and date, and the
Home City settings. If this does not correct the problem, refer to “Calibrating the High Tide Time” (page
E-102).
* The average tide graph uses a period of 12 hours 25 minutes from high tide to the next high tide,
assuming that low tide is between.
