INTRODUCTION
With your watch’s perpetual calendar feature, the date does not need adjustment until 2100. The watch automatically accounts for short months and leap years, always showing the correct day and date. The day and date were preset at the Timex factory. You only need to adjust the time. The watch has two recessed push buttons for use by Timex Service Center to set the day and date after battery replacement. They have no use otherwise.
LEAP YEAR OFFSET
To maintain the correct date, the watch includes a setting for the current leap year offset. This setting is made at the Timex factory or after battery replacement and cannot be changed, only viewed.
To view the offset, pull the crown to its middle position. The date hand shows the offset: 1 = 1 year after leap year; 2 = 2 years after leap year; 3 = 3 years after leap year; 4 = leap year. Push the crown in when done and the hands resume their normal display of day, month, and date.

BACK/RESET) to zero the chronograph and release it when you wish to restart. You do not have to wait for all hands to reach zero before releasing the button; the timing will start internally from the button release. This “fly-back” feature allows you to measure lap time.
The compass may be used while the chronograph is
running without interfering with its operation. See COMPASS OPERATION.
25
COMPASS CALIBRATION
Before use, the compass must be calibrated. Since a compass uses the earth’s magnetic field, you
must be aware of large metallic objects, such as vehicles or bridges, or objects that give off electromagnetic radiation, such as televisions or computers, which could affect the magnetic field around the watch. If the compass is calibrated near such objects, it will only work properly in that same location. If the compass is calibrated away from such objects, it will not work properly near them. For best results, calibrate in the area of intended use.
In calibrating and taking headings, it is important, as with all compasses, to keep the compass level. Calibrating or taking a heading when the watch is not level can result in large errors. Also avoid areas that may exhibit higher
26
than normal concentrations of hard and soft iron, as they may cause inaccurate headings. Whenever a heading is suspect, recalibrate.
Do not store the watch near any source of magnetism, such as a computer, appliance, or television, as the watch can take on a magnetic charge, yielding inaccurate headings. Typical accuracy of wrist-worn instruments is within +/- 10 degrees.
To calibrate the compass:
1. Pull the crown to its middle position and wait for the indicator hands to stop moving.
2. Keep the watch level or place it on a level surface (if the band interferes, place the watch on an inverted cup). The watch may be face down, but take care to protect the watch face.
27
3. Press C (COMPASS) to begin. The 4th center hand rotates two revolutions to remind you to rotate the watch. While level, SLOWLY rotate the watch two revolutions, taking at least 15 seconds per revolution.
4. When done, press C (COMPASS), keeping the watch level. The 4th center hand moves back and forth to acknowledge the end of calibration and then moves to the current magnetic declination setting.
28
5. If you do not wish to set the magnetic declination, push the crown in. Otherwise, to have watch automatically compensate for the declination angle, turn the compass ring until north is at 12 o’clock.
6. Press A or B to move the 4th center hand west (-) or east (+), respectively, to point to your location’s declination angle using the declination scale. Hold a button to move the hand quickly. See the figure below for an example.
7. Push the crown in when done.
A
Magnetic declination set to -14° (14°W)
29
COMPASS OPERATION
Normally, the compass is inactive, with the 4th center hand pointing to 12 o’clock or showing the chronograph seconds.
While holding the watch level, press C (COMPASS) to activate the compass. The compass hand moves to point north. If the watch is turned, the 4th center hand will continue to move, always pointing north. After 20 seconds, the compass will automatically turn off and the 4th center hand will return to its normal operation. This conserves battery life. Press C (COMPASS) at any time to keep the compass on for another 20 seconds.
The compass may be activated while the chronograph is in use. The 4th center hand merely switches operation temporarily. The upper and lower hands continue to show the chronograph time and all chronograph functions are
30
available through buttons A (START/STOP) and B (FLY­BACK/RESET).
NOTE: During compass operation, the second hand moves in two-second increments. Also, when the compass is activated, the upper and lower hands may shift position slightly, returning to their proper positions when the compass is deactivated. This operation is normal and yields the most accurate compass reading.

COMPASS CALIBRATION
Before use, the compass must be calibrated. Since a compass uses the earth’s magnetic field, you
must be aware of large metallic objects, such as vehicles or bridges, or objects that give off electromagnetic radiation, such as televisions or computers, which could affect the magnetic field around the watch. If the compass is calibrated near such objects, it will only work properly in that same location. If the compass is calibrated away from such objects, it will not work
46
properly near them. For best results, calibrate in the area of intended use.
In calibrating and taking headings, it is important, as with all compasses, to keep the compass level. Calibrating or taking a heading when the watch is not level can result in large errors. Also avoid areas that may exhibit higher than normal concentrations of hard and soft iron, as they may cause inaccurate headings. Whenever a heading is suspect, recalibrate.
Do not store the watch near any source of magnetism, such as a computer, appliance, or television, as the watch can take on a magnetic charge, yielding inaccurate headings. Typical accuracy of wrist-worn instruments is within +/- 10 degrees.
