Why is automatic time synchronization not working on my Seiko Watch?

  Courtney PhillipsAug 12, 2025
  Automatic time synchronization may not be performed if the automatic time synchronization mode is off in the application, pairing has not been done correctly, the watch and smartphone are not close, the application is open when the automatic time synchronization is performed, or sleep mode is on at the watch. Please make sure to synchronize after you turn on the Automatic time synchronization; otherwise, the Automatic time synchronization is not performed.
