FAQs

Does this watch require a battery?

No, the Citizen Tsuyosa features a Japanese automatic movement that is powered by the natural motion of your wrist. It does not require a battery.

How accurate is the automatic movement?

Automatic movements typically have a daily accuracy variance. The Citizen Tsuyosa is designed for reliable everyday timekeeping, with expected accuracy within industry standards for automatic watches.

Can I swim with this watch?

How do I maintain the watch's water resistance?

Always ensure the crown is pushed in or screwed down tightly before any water-related activity. Over time, the seals can degrade, so professional inspection during servicing is advised.

Troubleshooting

Watch stopped unexpectedly

Gently shake the watch for 30 seconds to restart the automatic movement. Ensure you wear the watch regularly or wind it manually if it has been stationary for an extended period.

Date not changing correctly

Ensure the time is not between 9 PM and 3 AM when setting the date. If the issue persists, consult the user manual or a professional watchmaker.

Bracelet feels loose or tight

Adjust the bracelet using the clasp mechanism or by removing/adding links (professional assistance may be required for link adjustment).
