About This Manual

•  Depending on the model of your watch, display text appears either as dark figures on a light background or light figures on a dark background. All sample displays in this manual are shown using dark figures on a light background.

Timekeeping
Use the Timekeeping Mode to set and view the current time and date. While Active Display is turned on, the  watch maintains a count that is incremented each time you angle it towards your face for viewing, or when you otherwise move your arm. The watch changes the Timekeeping Mode current time display to one of six different styles automatically in accordance with the value of the count.

•  Regardless of whether Active Display is turned on or off, tilting the watch towards your face for viewing will   cause the display figures change size, rotate, or otherwise change dynamically for approximately one second.   The way the display figures changes depends on the currently selected display style.
•  For more information about Active Display, see “Active Display”.
•  Holding down D in the Timekeeping Mode will display the current month, day, and day of the week. The   current time will return to the display about one second after you release D.
  

Time Display Formats
Your watch can display the current time using any one of the following display formats. 12 – 11: This 12-hour format does not distinguish between noon and midnight, which are both displayed as 12:00. 0 – 11: This 12-hour format does not distinguish between noon and midnight, which are both displayed as 0:00. 0 – 23: This 24-hour format distinguishes between noon (12:00) and midnight (0:00). 6 – 29: This 24-hour format uses a day that starts at 6:00 a.m. and ends at 5:59 a.m. The date changes at 6:00 a.m.
