Pull the crown out to the first click position and turn it to set the date. Avoid changing the date between 9 PM and 3 AM as it may interfere with the day-date cycle.
Clean your Seiko N877 watch using a soft, damp cloth for the case and band. Avoid using chemicals or submerging the watch in water if it is not water-resistant.
To replace the battery, open the case back carefully using a case opener tool. Remove the old battery and replace it with a new one, ensuring correct polarity. If unsure, consult a professional.
If your Seiko N877 is running fast or slow, it may need regulation or servicing. Environmental factors like magnetism can also affect its accuracy. Consult a watch technician for precise calibration.
Check the case back or user manual for water resistance markings. If the watch is rated, it will have a specific depth rating indicated (e.g., 50m or 100m).
If the crown is difficult to pull out, gently wiggle it while pulling. If resistance persists, consult a professional to avoid damaging the watch.
It is recommended to service your Seiko N877 watch every 3 to 5 years to ensure optimal performance and longevity.
