Step 2. At the end of the measured kilometer (mile), push and release button "A" again
Step 3. The Hand position, on the numbered scale at the dial perimeter, indicates your

HOW TO USE THE ELAPSED TIME INDICATOR
If your watch is equipped with a rotatable outer dial with one-minute gradua-
tions, this can be used in various ways to check elapsed time. For example if a
diver has a 30-minute air supply, he can set the outer ring so that the triangle is
in line with the minute hand when he submerges. The minute hand will then
indicate on the outer ring the length of time that the diver has been under water.

SCREW-DOWN CROWN

If your watch includes a screw-down crown, you have additional assurance that it will remain
watertight. To make the crown operational, it must be turned toward you until the threads are
disengaged. Then, instructions for setting must be followed. To reseal the crown, press in until
threads engage. Turn away from you until tight.
