The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also

applied in all modes.

The year can be set in the range of 2001 to 2098.

The watch’s built-in full automatic calendar automatically 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 battery replaced.

UTC

The letters “UTC” stands for “Universal Time Coordinated,” which is the world-wide standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep accurate to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation. The reference point for UTC is Greenwich, England.

Time Calibration Signal Reception Precautions

•This watch receives the time calibration signal (Call Sign: DCF77) transmitted from Mainflingen, Germany (located 25 kilometers southeast of Frankfurt). Signal

 

reception is possible within a radius of about 1,000

•

kilometers from the Mainflingen transmitter.

Signal reception may be poor in the shaded area on the

 

map, even though it is within 1,000 kilometers of the

•

signal transmitter.

The current time setting in accordance with the time

Frankfurt

calibration signal takes priority over any time settings

you make.

•

The Mainflingen time calibration signal includes summer

•

time (DST) data.

The watch is designed to automatically update the date

 

and day of the week for the period January 1, 2001 to

 

December 31, 2098. Setting of the date by the time

 

calibration signal cannot be performed starting from

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

•The display range of the stopwatch is 99 hours, 59 minutes, 59.99 seconds.

•The stopwatch measurement operation continues until you stop it or until it reaches 99:59' 59.99" (at which time the display resets to all zeros).

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

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

•

January 1, 2099.

This watch can receive signals that differentiate between

•

leap years and non-leap years.

Reception stops if an alarm starts to sound while the

 

signal is being received, and restarts after the alarm

•

operation is complete.

Even when the watch is within the reception range,

 

signal reception is impossible if the signal is blocked by

 

mountains or other geological formations between the

•

watch and signal source.

Signal reception is affected by weather, atmospheric

 

conditions, and seasonal changes.
