Tsuyosa Automatic Watch - Citizen - NJ015

No, the Tsuyosa Automatic watch is powered by an automatic movement that is wound by the motion of the wearer's wrist. It does not use a battery.

The watch has a power reserve of up to 40 hours, meaning it will continue to run for approximately 40 hours after being fully wound and not worn.

The watch has a 50-meter water resistance rating, which is suitable for protection against splashes and brief immersion in water. It is not recommended for swimming, diving, or prolonged water exposure.

Pull the crown out to the appropriate position(s) to set the time and date. Refer to the user manual for specific instructions on crown operation for your model. Avoid setting the date between 9 PM and 3 AM.

The watch features a highly scratch-resistant sapphire crystal with an anti-reflective coating for enhanced clarity.

Automatic watches generally benefit from servicing every 3 to 5 years to ensure optimal performance and longevity of the movement.

Please refer to the official Citizen warranty documentation included with your purchase for specific details on the warranty period and coverage.

The watch may have run out of power. Manually wind the crown by rotating it clockwise 30-40 times. Ensure you wear the watch regularly or wind it if it sits idle.

Ensure you are not trying to set the date between 9 PM and 3 AM. This is when the watch's date-changing mechanism is engaged, and setting it manually during this time can cause damage. Set the date outside of these hours.

Minor variations are normal for automatic movements. If accuracy deviates significantly (more than +/- 15-30 seconds per day), the watch may need adjustment or servicing by a professional watchmaker.

The sapphire crystal is highly scratch-resistant, but not indestructible. Deep scratches may require professional replacement by a watchmaker.
