We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. Equipped with Automatic & Manual Winding Function: This men's watch is equipped with the highly accurate Miyota 8215 automatic movement, which provides a long power reserve of over 41 hours. Since it is compatible with both automatic and manual winding, we recommend resetting with manual winding if you do not wear it for more than 42 hours. Reliable quality: Ergonomic design fits snugly on your wrist. The 316L stainless steel case has a durable PVD coating and scratch-resistant sapphire glass. The sophisticated blue, green, and black dial and matching waterproof silicone strap are both stylish and durable. Bi-directional rotating inner bezel: Operated by the crown at 2 o'clock, the bi-directional rotating inner bezel makes timekeeping simple and precise. The transparent scale and numbers are easy to read, and it also functions as a diver's watch, especially useful for time management when diving. Fluorescent markers, orange for the first 15 minutes and blue for the next 45 minutes, improve visibility and safety in the water. TRUSTED BRAND: BERNY has absolute confidence in the quality of our products. Customer satisfaction is our top priority and we provide customer service that responds quickly and with dedication to any inquiries. Important information: For automatic watches, when using them for the first time, they must be fully wound first. To fully wind the watch, rotate the crown approximately 30-40 turns clockwise, or wear it on your wrist for more than 8 hours. If the watch is not fully wound, it will lose time. Follow the steps above to check timing accuracy. If your automatic mechanical clock is displaying between 9pm and 4am, please do not adjust the date/date. This will be incorrect due to changes in the mechanism. You will need to readjust your calendar.
