TIMEWAVE / APP FEATURES
What you can do with TimeWave
A set of practical tools for preparing and reviewing a watch time-signal attempt.
Six signal station options
Choose from BPC, JJY40, JJY60, WWVB, MSF, and DCF77 station options across five radio time-signal systems. A watch must support the selected signal.
Standard and Enhanced playback
Use the standard profile or the premium Enhanced profile, which automatically adjusts playback frequency and volume.
Signal-specific variants
Try experimental standard or high-frequency BPC variants, or Classic Compatibility playback for JJY. Experimental modes are not a guarantee of reception.
Network time options
Use NTP-calibrated time, with cached network time and device time as fallbacks, or choose the device clock directly.
Environment checks
Review phone volume, battery level, ambient noise, and magnetic-field readings before an attempt.
Guidance and history
Follow phone, watch, brand, and placement guidance, then review saved sync-attempt history.
Audio route adjustments
Playback tuning adapts to the detected built-in speaker, wired audio, or Bluetooth route. Results vary by hardware.
Seven app interface languages
The app includes English, Japanese, Simplified Chinese, Traditional Chinese, German, Korean, and Arabic.
