The Eco-Drive light-powered movement uses a rechargeable power cell, not a traditional battery. With proper care and regular light exposure, the power cell can last for many years, often exceeding a decade, before requiring replacement.
First, set the main hour and minute hands to the local time. Then, use the crown to adjust the GMT hand to display your reference time zone. Consult the specific user manual for your model for detailed steps.
GMT stands for Greenwich Mean Time, a time standard that is now used as a primary reference for the world time. In watches, a GMT function allows you to track a second time zone in addition to your local time.
The 39mm case diameter is generally considered a medium or classic size. While it fits many wrists comfortably, personal preference varies. It's recommended to try one on if possible or check wrist size guides.
Yes, with 200 meters of water resistance and ensuring the crown is fully secured, the watch is suitable for swimming, snorkeling, and other water sports.
Use a soft, damp cloth to wipe down the bracelet. For tougher grime, a mild soap solution can be used, followed by a thorough rinse with fresh water and drying with a soft cloth. Ensure no water enters the watch case.
No, this watch features Eco-Drive technology and is powered by light. It does not require manual winding or battery changes.
Expose the watch to a sufficient light source for several hours to recharge the Eco-Drive cell. If the issue persists after a full charge, contact customer support.
Ensure the local time is set correctly first, then set the GMT hand independently using the crown. Refer to the user manual for precise instructions on setting the GMT hand.
While the watch has luminous markers, in very dark conditions, ensure it has been exposed to light recently to maximize luminescence. Clean the crystal to ensure maximum light transmission.
Ensure the crown is fully secured. If the watch has been submerged with the crown open or if water ingress is suspected, cease use immediately and seek professional servicing.
Setup: The primary setup involves setting the local time and date. To set the GMT hand, first, set the local time. Then, use the crown to independently move the GMT hand to your desired second time zone. For the Eco-Drive to function optimally, expose the watch to light regularly. A full charge from empty can take several hours of direct light, but daily wear in natural or artificial light will keep it sustained.
Compatibility: This watch is a standalone analog timepiece and does not interface with digital devices. Its compatibility is universal for wrist wear.
