Description
CASIO OCEANUS OCW-T200S-1AJF — Classic Line Solar Radio-Controlled Watch
The CASIO OCEANUS OCW-T200S-1AJF combines a refined three-hand design with Tough Solar charging, Bluetooth smartphone connectivity and radio-controlled timekeeping. Made in Japan, this Japanese domestic market model features a black dial with distinctive blue accents, a stainless steel case and bracelet, and an anti-reflective sapphire crystal.
Black Dial with Signature OCEANUS Blue
The clean black dial provides a sophisticated setting for the three-hand display and date window. Blue vapor deposition on the inner bezel introduces the signature OCEANUS color without overwhelming the understated design. A flat bezel and a combination of brushed and polished metal surfaces make the watch suitable for both business and casual wear.
Stainless Steel and Sapphire Crystal
The stainless steel case and solid-link bracelet receive titanium carbide surface treatment. The sapphire crystal features an anti-reflective coating on its inner surface for improved dial visibility, while Neobrite luminous elements help with reading the time in low light after exposure to light.
The case measures 49.5 × 41.4 × 10.7 mm, and the watch weighs approximately 133 g. A three-fold clasp with push-button release secures the bracelet, which accommodates wrist sizes from 150 to 195 mm.
Tough Solar and Radio-Controlled Timekeeping
Tough Solar converts sunlight and artificial light into energy to recharge the internal battery. The watch also receives compatible time calibration signals transmitted from Japan, the United States, the United Kingdom, Germany and China for automatic time adjustment. Signal reception depends on your location, surroundings and time zone settings.
After a full charge, the watch operates for approximately five months without further light exposure under the specified usage conditions, or approximately 20 months in the specified power-saving conditions. When radio reception and smartphone time correction are unavailable, the watch operates with an average accuracy of ±15 seconds per month.
Bluetooth Smartphone Connectivity
Bluetooth Mobile Link connects the watch to a compatible smartphone through the CASIO WATCHES app. Supported functions include automatic time correction, time zone and daylight saving time adjustment, battery status checking, hand alignment correction and phone finder. Automatic hand position correction also helps maintain accurate hand alignment.
