• Resetting the seconds only (without changing the hour, minute, or DST setting) causes the analog minute hand setting to be adjusted automatically. If you change the hour, minute, or DST setting, you should also use the procedure under “To adjust the analog time” to adjust the analog hands accordingly. See “Digital Time Daylight Saving Time (DST) Setting” for details about the DST setting.
• Resetting the seconds to AA while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to AA without changing the minutes.
• The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.
