FOR THE AUTOMATIC SELF-WINDING MECHANICAL WATCH: It must be wound at least six or seven times before you wear it. After that, your daily activity should wind the watch sufficiently to keep it running at night when it is not being worn. If your normal daily activity is not sufficient, occasional supplementary manual winding may be neces-sary. It is suggested that your mechanical watch be cleaned and oiled periodically to insure optimum performance. As a mechanical watch, quartz watch accuracy cannot be expected. References to the power cell do not apply to Automatic watches. 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 watch should be brought to an authorized Bulova dealer for replacement of the power cell. For best performance, the proper power cell should be used. Note: When the crown is in the “OUT” position, the motor and hands stop. Only the quartz crystal continues to vibrate, using very little power. If the watch is to be stored for a length of time, it is recommended that the crown be left in the “OUT” position to prolong battery life. WATER RESISTANCE Watch models marked only “Water Resistant” on the case back, without additional depth mark-ings are not to be used for swimming. For swimming, models that have the additional marking of “50m,” “100m” or “200m” are recommended.
