8.4 Glossary
In Compass mode the watch indicates magnetic north. Other display modes are available, such as
indication of geographic north or azimuthal direction.
On a geographical map of the world, the vertical lines (meridians) converge towards the Geographic
North Pole(gN), thus indicating its direction. The needle on a standard compass, which is often red,
points towards the North Magnetic Pole (mN). The angle (α) between these two directions, gN and
mN, is called the magnetic declination. The value of the magnetic declination thus depends on where
you are on the globe.
In addition, the North Magnetic Pole is constantly shifting. The magnetic declination value thus also
depends on the date. When the correct (for location and date) magnetic declination value is set, either
automatically or manually (see setting procedure under the "T-Touch" heading), the T-Touch Connect
Solar’s minute hand points towards geographic north (gN). When magnetic declination is reset to zero,
the watch points to magnetic north (mN).
Magnetic declination values and dates are shown on topographical maps or can be looked up in
dedicated software packages available online.
