Magnetic (and True with
Bezel
set) Compass & Bubble Level South West 204 degrees at 9:47 am The Bezel is turned about 15 degrees to allow an estimation of True North. When the compass reads 0 or 360 the bezel "N" is where True North is located. Note: In order for the compass to read correctly the bubble level needs to be centered. Here the watch is out of position. |
