Timekeeping (Based on a Time Calibration Signal)
Appropriate Signal Reception Location (Time Calibration Signal)
- Keep the watch away from metal and position it so its 6 o’clock side is facing a window. Avoid moving the watch as much as possible and do not perform any watch operations while a signal receive operation is in progress.
You may experience time calibration signal reception problems in the areas described below.
- Among or near buildings
- While riding in a vehicle
- Near household appliances, office machines, mobile phones, etc.
- On a construction site, in an airport, or any other location where radio wave interference occurs
- Near high-voltage lines
- In mountainous areas or behind a mountain
Always check the time setting on the day there should be a switch between standard time and summer time (DST). If the setting is not correct (due to signal reception failure), turn DST on or off manually as required.
Time Calibration Signal Auto Receive
Important: To perform time calibration signal auto receive, the watch must be in the Timekeeping Mode. See “Mode Reference Guide” (page E-12).
- Leave the watch in a location that is appropriate for time calibration signal reception between the hours of midnight and 5:00 a.m. See “Appropriate Signal Reception Location (Time Calibration Signal)” (page E-9).
- The second hand will point to RC while the time calibration signal reception is in progress.
- Reception normally takes anywhere from about two to ten minutes, but it can take as long as 20 minutes.
- When the receive operation is successful, the time and day settings will be adjusted automatically.
Time Calibration Signal Manual Receive
- Hold down B for at least two seconds until the second hand moves to RC (Receive). If the second hand is a position other than RC, keep B depressed until it moves to RC.
- Place the watch near a window.
- The time setting will be adjusted automatically when a signal receive operation is successful.
- Calibration signal reception normally takes anywhere from about two to 10 minutes. It can take as long as 20 minutes.
- The best reception is in the middle of the night.
Mode Reference Guide
- Use C to navigate between modes.

Using the Watch in a Medical Facility or Aircraft
- Disable auto time adjustment whenever you are in a medical facility, and aircraft, in any other area where radio wave reception and connection with a phone are prohibited or restricted.

To disable auto time adjustment, rotate the crown to move the second hand to N (NO). To enable auto-time adjustment, rotate the crown to move the second hand to Y (YES). After the setting is the way you want, push the crown back in to its normal position.
