What is Magnetic Declination
+
The Magnetic North Pole which is slightly
different from the True North Pole. This Watch,
like most magnetic compass, points to the
Magnetic North Pole, while everything measure
from a map is related to the True North Pole.
+
The angular difference between Magnetic
North Pole and True North Pole is called
magnetic declination. Its amount (degrees and
minutes) and direction (easterly and westerly)
depend on where you are in the world.
+
For serious compass user or whom intends to
perform accurate navigation, this Watch must
be adjusted for magnetic declination.
Magnetic Declination Information
+
Most topographic maps include a small arrow
which shown magnetic north pole and or the
magnetic declination information.
+
This manual includes the magnetic declination
for some major cities. See the coming chapter
'Magnetic Declination at Major Cities' for more
detail.
+
For the cities are not included in the list,
please refer to the online magnetic declination
calculator at:

Examples
+
To get an object's true bearing (TB) by
subtract westerly (W) magnetic declination
or add easterly (E) magnetic declination
with the magnetic bearing (MB).
+
Exa m p l e 1: 2 3 8 We ster l y magnet i c
declination and the compass needle points
323 .
+
TB = MB - W. While MB = 323 ; W =23
+
TB = 323 - 23
+
TB = 300
+
The true bearing will be 300 .
+
Example 2: 2 2 E a s t e r l y m a g n e t i c
declination and the compass needle points
278 .
+
TB = MB + E. While MB = 278 ; E = 22
+
TB = 278 + 22
+
TB = 300
+
The true bearing will be 300 .
+
The Watch can compensate the compass
bearing at a place where the magnetic
declination is either Westerly declination or
Easterly declination.
