Daylight Saving Time (DST) Setting

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight

Setting the Time and Date

This watch is preset with UTC differential values that represent each time zone around the globe. Before setting the time, be sure to set the UTC differential for your Home Site first, which is the location where you normally will be using the watch.

•Note that World Time Mode times are all displayed based on the time and date settings you configure in the Timekeeping Mode.

To set the time and date

				1. In the Timekeeping Mode, hold down Auntil the
				seconds start to flash, which indicates the setting

Home Site Data

Moon phase, tide graph data, and Tide/Moon Data Mode data will not be displayed properly unless Home Site data (UTC differential, longitude and lunitidal interval) is configured correctly.

•The UTC differential indicates the time differential with Greenwich, England.

•The letters UTC is the abbreviation for Coordinated Universal Time, which is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

•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 UTC differential and longitude 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.

UTC differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours, 20 minutes)
