COMPASS RING
If your watch is equipped
with a movable ring around
the dial marked at the letters
“N”, “E”, “W”, “S” (for the four
compass directions) or com-
pass degrees, you can use this fea-
ture to find an approximate compass
directional reading.
1) Lay the watch on a flat surface,
or hold it so that the face is
parallel to the ground.
2) Locate the sun and point the
hour hand at the sun.
3) In the A.M., rotate the ring until the “S” (south)
marker is halfway between the hour hand and
12:00 (after the hour hand or within the shortest
distance between the hour hand and 12:00).
4) In the P.M., rotate the ring until “S” is before the
hour hand and halfway between the hour hand
and 12:00.

TACHYMETER RING
The tachymeter feature can be used to measure
speed in miles per hour (MPH), nautical miles per
hour (knots) or kilometers per hour (KPH) using the
sweep second hand and the scale on the wall above
the watch face. You need to know the actual dis-
tance you are covering in miles or km.
Start the chronograph with the second hand at zero
(the twelve o’clock position). Within the first minute,
the second hand will point to the rate for a one-mile
(or one kilometer) course: if it takes 45 seconds, the
hand will point to 80 at that position – 80 MPH or 80
KPH.
If within the first minute, a distance greater than one
mile or kilometer is covered, multiply the tachymeter
number by the distance to get the actual rate: if you
went 1.2 miles in 45 seconds, multiply the 80 by
1.2 – 96 MPH.
