FAQs

How long does the Eco-Drive power reserve last?

The power reserve duration varies depending on the specific model and its last full charge. Many Eco-Drive models can run for months on a full charge, even in complete darkness.

Do I need to replace the battery on this watch?

No, the Eco-Drive technology means the watch is powered by light and does not require traditional battery replacements. It uses a rechargeable light-energy battery.

What is the warranty period for this watch?

This watch comes with a 2-year warranty from the date of purchase, covering manufacturing defects.

Can I wear this watch while swimming?

Yes, with a 10 bar water resistance rating, this watch is suitable for swimming and showering. However, it is not recommended for scuba diving or high-velocity water sports.

How do I set the chronograph function?

The chronograph functions (start, stop, reset) are typically operated by the pushers located above and below the crown. Refer to the specific user manual for detailed instructions on using the stopwatch feature.

What kind of light is best for charging the watch?

Any light source can charge the watch, but natural sunlight is the most efficient. Artificial light sources also work, though they may take longer to achieve a full charge.

What is the strap made of and how is it secured?

The strap is made of durable urethane and is secured with a buckle clasp.

Troubleshooting

Watch has stopped or is not keeping time.

The watch needs to be charged. Expose it to a bright light source (sunlight is best) for at least 8 hours. If it has a power reserve indicator, check its level. Ensure the crown is pushed in fully.

Chronograph function not resetting to zero.

Ensure the chronograph is fully reset. Refer to the watch's manual for specific reset procedures for the chronograph hands.

Date is not changing correctly.

Ensure the time is set correctly between AM and PM. The date typically changes at midnight. Adjust the date using the crown's setting positions as per the manual.

Condensation under the crystal.

This may indicate a breach in water resistance. Contact an authorized Citizen service center for inspection and repair.
