2. Opsætning og første idriftsættelse
2.1 Unboxing and Initial Winding
Upon receiving your Citizen Tsuyosa watch, it may not be running. As an automatic watch, it requires kinetic energy to operate. To start the watch:
- Gently shake the watch from side to side for about 30 seconds to initiate the automatic winding mechanism.
- Alternatively, you can manually wind the watch by rotating the crown in the normal position (position 0) clockwise for approximately 20-30 turns. This will build up a sufficient power reserve to start the movement.

2.2 Indstilling af tid og dato
The crown has three positions:
- Position 0 (Normal): For manual winding.
- Position 1 (First Click): For setting the date.
- Position 2 (Second Click): Til indstilling af tiden.

- Indstilling af dato:
- Pull the crown out to Position 1 (first click).
- Rotate the crown clockwise or counter-clockwise until the desired date appears in the date window.
- Avoid setting the date between 9:00 PM and 3:00 AM, as this can damage the date mechanism. If the time is within this period, first set the time outside this range, then set the date, and finally reset the time.
- Skub kronen tilbage til position 0.
- Indstilling af tid:
- Pull the crown out to Position 2 (second click). The second hand will stop.
- Rotate the crown to move the hour and minute hands to the correct time. Ensure you set the correct AM/PM by observing if the date changes when the hour hand passes 12.
- Once the time is set, push the crown back to Position 0. The second hand will resume movement.
3. Operating Your Automatic Watch
3.1 Automatic Winding Mechanism
Your Citizen Tsuyosa watch is powered by an automatic mechanical movement (Caliber 8210). This means it is wound by the natural motion of your wrist. As you wear the watch, an oscillating weight inside the movement rotates, winding the mainspring and storing energy.

3.2 Gangreserve
When fully wound, your watch has a power reserve of approximately 42 hours. If the watch is not worn for an extended period, it will stop. To restart it, follow the initial winding instructions in Section 2.1.
Regular daily wear is usually sufficient to keep the watch wound. If your daily activity is minimal, occasional manual winding (20-30 turns of the crown in Position 0) may be necessary to maintain the power reserve.
4. Vedligeholdelse og pleje
4.1 Vandtæthed
Your Citizen Tsuyosa watch is water resistant to 50 meters (5 ATM). This rating means it is suitable for short periods of recreational swimming, showering, or washing hands. It is ikke suitable for diving, snorkeling, or prolonged water immersion.
- Always ensure the crown is fully pushed in to Position 0 before any contact with water.
- Do not operate the crown or pushers (if any) while the watch is wet or submerged in water.
- Avoid exposing the watch to extreme temperature changes, such as moving from a hot sauna to cold water, as this can affect the water resistance seals.
- Efter udsættelse for saltvand, skyl uret med ferskvand og tør det grundigt med en blød klud.
4.2 Rengøring af dit ur
Sådan bevarer du dit urs udseende:
- Wipe the case and bracelet regularly with a soft, dry cloth to remove dust, sweat, and fingerprints.
- For dele i rustfrit stål, en let damp klud kan bruges, efterfulgt af øjeblikkelig tørring.
- Undgå at bruge kemiske rengøringsmidler, opløsningsmidler eller slibende materialer, da disse kan beskadige overfladen.
4.3 Sapphire Crystal Care
The watch features an anti-reflective sapphire crystal, known for its high scratch resistance. While highly durable, it is not entirely scratch-proof or shatter-proof. Avoid impacts and contact with extremely hard or sharp objects.
5. Fejlfinding
- Uret er stoppet eller går unøjagtigt:
This is typically due to insufficient power reserve. Ensure the watch is worn regularly or manually wound (20-30 turns of the crown in Position 0) to build up sufficient power. If the issue persists after proper winding, contact customer support.
- Date does not change at midnight:
The watch may be set to PM instead of AM. Advance the time by 12 hours. Also, ensure you are not attempting to set the date between 9:00 PM and 3:00 AM, as this can interfere with the date change mechanism.
- Kondensation inde i krystallen:
Small amounts of condensation that disappear quickly are usually not a concern. However, if condensation persists or appears as large droplets, it indicates a loss of water resistance. Immediately take the watch to an authorized service center to prevent internal damage.
