The stopwatch lets you measure elapsed time, split times, and two finishes.

•The display range of the stopwatch is 59 minutes, 59.99 seconds.

•The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.

•The stopwatch measurement operation continues even if you exit the Stopwatch Mode.

•Exiting the Stopwatch Mode while a split time is frozen on the display clears the split time and returns to elapsed time measurement.

•All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.

•If you leave the watch in the e-DATA MEMORY, City Temperature, or Alarm Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode.

•If you leave a screen with flashing digits or a cursor on the display for two or three minutes without performing any operation, the watch automatically saves any settings you have made up to that point and exits the setting screen.

Scrolling

The Band D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls at high speed.

Initial Screens

When you enter the e-DATA MEMORY, World Time, or City Temperature Mode, the data you were viewing when you last exited the mode appears first.

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

Timekeeping

•Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

•The year can be set in the range of 2000 to 2039.

•The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s batteries replaced.

World Time

•The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.

•The world time that appears in the Timekeeping Mode screen always uses 24-hour format, regardless of the watch’s current 12/24-hour setting.

•The current time in all World Time Mode cities is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on the current Home City time setting in the Timekeeping Mode.

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

•GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data.

Illumination Precautions

The display of the watch is illuminated by an LED (light-emitting diode) and a light guide panel for easy reading in the dark.

In any mode (except when a setting screen is on the display), press B to illuminate the display for about two seconds.

•Illumination may be hard to see when viewed under direct sunlight.

•Illumination turns off automatically whenever an alarm sounds.

•Frequent use of illumination runs down the batteries.
