Compass explanations
The vertical lines (meridians) on the Earth converge at the True North Pole (Ng),
indicating its direction. The hand of a conventional compass indicates the direc- | ||
tion of the Magnetic North Pole (Nm). The angle |
| |
between these two directions Ng and Nm is known |
| |
as magnetic declination. The magnetic declination | Ng | |
value depends on your location on Earth. Fur- | ||
Nm | ||
thermore, the Magnetic North Pole is constantly | ||
moving. So the magnetic declination value also de- |
| |
pends on the date. If the correct magnetic declina- |
| |
tion value (for the location and date) is set (see the |
| |
setting procedure on page 11), the minutes hand |

Note 1
For a correct indication of North, it is very important to hold the watch as level as possible.
Note 2
The compass function, like any other compass, should not be used near a metal or magnetic mass. In case of doubt, you can recalibrate your compass.
