 • In Dual Time Mode, Press and 

Hold [ MODE ] for 2 seconds 
until the "minutes" digits flash

 •  Press [ MODE ] to navigate to 

the setting that you wish to 
change. See navigation chart at 
right

 • When the setting you wish to 

change flashes, Press [ ST/STP ] 
to raise the value or [LAP/RESET] 
to lower the value. 

Note: If you Press and Hold the 

button, the rate of change is 
faster

• When the hour is set, Press        

[ MODE ] to confirm and return to 
the Dual Time Mode

NOTE: If NO INPUT for 1 minute 

during the setup, the display will 
default to the Dual Time Mode

 
This watch is a digital compass that provides directions, bearings and 

Magnetic North Pole location.

Caution: Accurate readings will be compromised when used near 

magnetic fields, mobile phones, speakers, motors, electrical 
appliances and inside a moving vehicle or a ferroconcrete building. 

Watch may need to be calibrated for 

declination

 

Perform calibration when:

 

• first time of use     

 • 

DIST is flashing

 

• Declination has changed

 

• Battery has been changed 

Compass Display
To access, press [ LAP/RESET ]  when in 

current time mode.

• Compass direction  - displays in 1st 

row

• Compass bearing - displays in 2nd row
• Animated cardinal points - display in 

perimeter bar graph

 

 

Compass Standby Mode
• To extend battery life, watch will 

switch to standby mode if there is NO 
INPUT for 1 minute when in compass 
mode

• Press any button except [ LIGHT ] to 

exit standby mode

 • In the Compass Mode, Press 

and Hold [ MODE ] for 2 
seconds. DEC will display in 
the 1st row and the digits will 
flash

• Press [ ST/STP ] to set 

desired declination angle (-90 
to +90)

 • Press [ MODE ]  CAL will 

display in the 1st row and the 
north pole pointer will move

 • Lay the watch on a level 

surface. Steadily rotate the 
watch counter-clockwise 
twice. Keep the pointer in the 
same direction through out 
the rotation 

 • Press [MODE] to confirm and 

return to Compass Mode

    on the continent. Where True and Magnetic North are in the same direction, the 

declination is zero. At any  point west of that line, your compass needle will 
point east of True North. This is called “Easterly Declination.” At any point east 
of that zero line, your compass needle will point west of True North. This is 
called “Westerly Declination.” 

The Magnetic sensor in the compass is 

attracted by the magnetism of the 
Earth and therefore, always points to 
the constantly shifting Magnetic 
North. There is another “North Pole.” 
True North is static and located 
geographically about 800 miles 
north of the magnetic pole. Maps 
and directions usually are based on 
True North. Magnetic declination is 
the angle between True North and 
Magnetic North. The amount of 
declination at any given point 
depends on the location of that 
point. 

 
The watch will automatically make declination compensation. We have 

included a list of the declination angles of North America. In the 
Declination Setting Mode, input the closest angle and the watch will 
make the adjustment.
