Extended Product Information
FAQs
Does this watch require a battery?
No, the Citizen Tsuyosa Automatic watch is powered by an automatic mechanical movement. It is wound by the natural motion of your wrist. If the watch has stopped, you can manually wind it by turning the crown clockwise.
What is the water resistance of this watch?
The watch has a water resistance of 50 meters (5 ATM). This rating is suitable for daily wear, such as protection against accidental splashes or rain, but it is not recommended for swimming, diving, or showering.
How accurate is the automatic movement?
Automatic movements, like the Caliber 8210 used in this watch, typically have a daily accuracy variance. For this movement, you can generally expect accuracy within +/- 15 to 30 seconds per day, though this can vary based on usage and maintenance.
Can I change the bracelet to a different strap?
The Tsuyosa features an integrated bracelet. While strap changes are possible, the lug design may limit options. It's best to consult with a watch professional or jeweler to find compatible straps.
How do I clean the stainless steel bracelet?
Clean the stainless steel bracelet using a soft, damp cloth. For tougher grime, use mild soap and water, then rinse thoroughly and dry completely with a clean, soft cloth. Avoid abrasive cleaners.
What is the power reserve of the movement?
The Citizen Caliber 8210 automatic movement typically has a power reserve of approximately 40 hours when fully wound. This means it will continue to run for about 40 hours after being fully wound if left stationary.
What does 'See Through Case Back' mean?
A 'See Through Case Back' (also known as an exhibition case back) is a transparent cover on the back of the watch, usually made of glass, that allows you to see the inner workings of the automatic movement.
Troubleshooting
Watch stopped or losing time significantly.
Ensure the watch has been fully wound by wearing it for a full day or manually winding the crown. If the issue persists, the movement may require servicing.
Date is not changing correctly.
Avoid setting the date between 9 PM and 3 AM, as this can damage the movement. Manually advance the time past midnight to reset the date if it is stuck.
Luminous markers/hands are not glowing.
Luminosity requires 'charging' from light. Expose the watch to a bright light source for a few minutes. The glow will naturally fade over time.
Crown is difficult to turn or pull out.
Ensure you are pulling the crown straight out. If it feels stiff, do not force it. The watch may require professional inspection.

Setup, Compatibility & Care
Initial Setup:
- Winding: If the watch has stopped, gently wind the crown (located on the right side of the case) clockwise about 30-40 times until you feel resistance. Avoid overwinding.
- Setting Time and Date: Pull the crown out to its first position to set the date. Pull it out to the second position to set the time. Ensure you set the date correctly, avoiding changes between 9 PM and 3 AM.
Compatibility:
- Bracelet Adjustment: The stainless steel bracelet can be adjusted for size by a qualified jeweler or watch technician who can remove or add links.
- Strap Replacement: While the integrated bracelet offers a distinct look, strap replacement might be limited due to the lug design. Consult a professional for compatible strap options if desired.
Care and Maintenance:
- Cleaning: Clean the stainless steel case and bracelet with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials. Dry thoroughly.
- Water Resistance: The 50m water resistance is sufficient for accidental splashes but not for submersion. Avoid exposing the watch to high-velocity water (like from a faucet) and do not operate the crown while wet.
- Storage: Store the watch in a cool, dry place. If not worn regularly, consider using a watch winder to keep the automatic movement running.
- Servicing: It is recommended to have the watch professionally serviced every 3-5 years to ensure optimal performance of the automatic movement.
