I purchased this at Yodobashi Camera in 2021. The battery is dead, so please just replace the battery. I believe the functionality is fine. Retail price: ¥143,000 (tax included) [Product Description] This is a classic line from OCEANUS, which pursues quality and multi-functionality under the brand concept of "Elegance, Technology." The case and band are DLC-coated for high abrasion resistance. The overall black color emphasizes the blue, which is the brand color of OCEANUS. The wide face dial is easy to read, and the layered dial creates a three-dimensional effect. High-quality finishing is applied to every detail, such as the Zaratsu polishing that requires skilled techniques and the surface hardening of the case and band by titanium carbide treatment. Furthermore, it is equipped with a dual dial world time function, allowing simultaneous display of the time in two cities: home time and world time. With an ultra-small 6-motor and smart access, the world time city can be quickly changed with easy crown operation, and daylight saving time is also set automatically.
