Home Site Data
Tide graph data 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 a meridian
and the next high tide at that meridian. See “Lunitidal Interval” for more information.
• This watch displays lunitidal intervals in terms of hours and minutes.
• The “Site/Lunitidal Interval Data List” provides GMT differential, longitude, and
lunitidal interval information around the world.
• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch and whenever you have the battery replaced. Change these
settings to match the area where you normally use the watch.
GMT differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours,

and beeper alert” below.
• For information about countdown timer alerts, see “Countdown Timer”.
• For information about the daily alarm and hourly time signal alerts, see “Alarms”.
• Watches with a metal band may produce a noise when a vibration operation is
performed. This is due to vibration of the metal band, and does not indicate
malfunction of the watch.
