To set the time on your Citizen H990 watch, pull the crown out to the second click position. Rotate the crown to adjust the time. Once set, push the crown back in to start the movement.
If your Citizen H990 watch stops working, it may need a recharge. Place the watch in direct sunlight for several hours. If the watch still does not function, contact an authorized service center for further assistance.
To adjust the date, pull the crown out to the first click position. Rotate the crown to set the correct date. Ensure the time is not set between 9 PM and 3 AM to avoid damaging the date mechanism.
To maintain water resistance, ensure the crown is always pushed in and screwed down tightly. Avoid exposing the watch to hot water or steam. Have the water resistance checked by a professional every two years.
If your watch is not charging, ensure it is exposed to sufficient light. Avoid using artificial light sources, as they may not provide enough energy. If issues persist, the rechargeable battery may need replacement.
To reset the chronograph, ensure the chronograph is stopped, then press the reset button. If it does not reset to zero, refer to the manual for calibration instructions or contact support.
While band replacement can be done at home with the right tools, it is recommended to have it done by a professional to avoid damaging the watch or compromising its water resistance.
Use a soft, damp cloth to gently wipe the watch. Avoid using cleaning agents or submerging the watch in water. For a thorough cleaning, have it serviced by a professional.
Signs that your watch needs servicing include losing time, the crown being difficult to turn, or the watch not holding a charge. A regular check-up every 3-5 years is recommended.
If the hands are misaligned, they may need recalibration. Refer to the manual for hand alignment instructions or take the watch to an authorized service center.
