8. Calculation of crosswind:
Using the graph (engraved on the case back) de-
termine the point of intersection of the wind speed
(head/tailwind component) and the crosswind angle.
Going from the point of intersection, read the value
of the crosswind component on the horizontal axis.
Ex. Headwind component: 40 mph
Crosswind angle: 30°
Crosswind component: 20 mph
9. Calculate the angle of drift:
Locate the crosswind component (20) on the exterior
rotating bezel and read the value indicated on the
interior bezel.
Ex. Angle of drift: approx. 6.5°
10. Calculation of corrected bearing:
If the wind is blowing from the right, add the angle of
drift to the magnetic bearing.
If the wind is blowing from the left, subtract the angle
of drift from the magnetic bearing.
Ex. Corrected bearing: 40° + 6.5° = 46.5°
For memorization, use the
crown
E
to indicate the cor-
rected bearing (46.5) on the
lower interior rotating bezel.
IMPORTANT: In order to ensure
the water-resistance of your watch, always screw the
crowns back in after any manipulation of them.
