FAQs
How does the Eco-Drive technology work?
Eco-Drive technology utilizes a solar cell that converts light energy (natural or artificial) into electrical energy, which is stored in a rechargeable power cell. This eliminates the need for traditional battery replacements.
How often do I need to charge the watch?
Under normal use, the watch should maintain its charge when exposed to light regularly. A full charge can power the watch for several months in darkness. For optimal performance, ensure it receives ambient light daily.
What does 'Radio Controlled' mean for timekeeping?
Radio Controlled means the watch can automatically receive time signals broadcast from radio towers. This allows it to maintain extremely accurate time, automatically adjusting for daylight saving time and time zones when properly set.
Can I wear this watch while swimming?
Yes, the watch has a water resistance of 10 bars (100 meters), making it suitable for swimming, showering, and other water-related activities. However, it is not designed for deep diving.
What is the warranty period for this watch?
The watch comes with a warranty of 2 years from the date of purchase, covering manufacturing defects.
How do I adjust the stainless steel strap?
Strap adjustment typically involves a professional jeweler or watchmaker who can add or remove links. Some clasps may have micro-adjustment settings. Please consult your user manual or a professional for precise adjustments.
What does the tachymeter function do?
The tachymeter is a scale on the bezel or dial that allows you to measure speed over a known distance. For example, if you travel one kilometer, you can read your average speed in kilometers per hour from the tachymeter scale.
Troubleshooting
Watch is not running or hands are stopped.
Expose the watch to a bright light source for at least a few hours to recharge the Eco-Drive power cell. If the issue persists, check the user manual for specific reset procedures or contact customer support.
Time is inaccurate or not synchronizing with radio signals.
Ensure the watch is in an area with good radio signal reception, away from electronic interference. Try manually initiating a time reception. Check that the correct home city is set in the watch's settings. If using the watch for the first time or after a long period of darkness, it may take multiple synchronization attempts.
Chronograph hands are not returning to zero.
The chronograph may need to be reset. Refer to the user manual for instructions on how to reset the chronograph's sub-dials back to their zero positions.
Water has entered the watch case.
Immediately stop using the watch and take it to an authorized service center for inspection and repair. Do not attempt to dry it yourself, as this can cause further damage.

Setup, Compatibility & Care
Initial Setup: Upon receiving the watch, expose it to a bright light source for several hours to ensure the Eco-Drive power cell is fully charged. For radio-controlled models, you may need to manually initiate a time reception or set the home city for accurate time zone synchronization. Refer to the user manual for specific instructions related to your region.
Compatibility: This watch is designed as a standalone timekeeping device. Its compatibility is primarily with the user's wrist and general environmental conditions. Ensure it is exposed to light regularly to maintain its charge.
Care: Clean the watch case and stainless steel strap regularly with a soft, damp cloth. Avoid exposing the watch to harsh chemicals, extreme temperatures, or strong magnetic fields. Ensure the crown is pushed in or screwed down (if applicable) to maintain water resistance. Periodically check the strap and clasp for any signs of wear.
