Important!
• When getting ready to receive the time calibration signal, position the watch
as shown in the nearby illustration, with its 12 o'clock side facing towards a
window. This watch is designed to receive a time calibration signal late at
night. Because of this, you should place the watch near a window as shown
in the illustration when you take it off at night. Make sure there are no metal
objects nearby.
• Make sure the watch is facing the right way.
