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.
LOCKING PUSH BUTTONS (ON SOME MODELS)
When the watch is submerged, this feature allows you to lock the push buttons for the chrono-
graph so that they cannot be pushed accidentally. To lock the buttons, simply turn the outer
collar of the button clockwise until it is fully seated against the button recess in the case. Then,
test the button to insure it cannot be pushed in. Reverse the process when needed.
ABOUT THE POWER CELL
Your new Quartz Watch has a fresh power cell designed to provide maximum reliability for
approximately a year under normal use. If the cell is not replaced before it is exhausted, the
watch will simply stop. The mechanism should not be harmed in any manner. However, when
the power cell becomes exhausted, it should be removed at your earliest convenience to dimin-
ish the possibility of leakage. Never store your watch with an exhausted power cell in it. The
