Casio Oceanus Cachalot OCW-P3000-3AJF JDM Titanium and Green Ceramic Watch (42.9 mm, Solar-Powered, Multiband 6 Radio-Controlled, Bluetooth, Double AR-Coated Sapphire Crystal, Zaratsu Polished, Made in Japan)

The Casio Oceanus Cachalot OCW-P3000-3AJF is exclusively available in the Japanese domestic market (JDM) and is assembled at the Premium Production Line in Yamagata, Japan. It stands out for its green dial combined with the lightness of solid titanium hardened with titanium carbide (weighing just 99 grams) and a rotating bezel with a two-tone ceramic insert that visually distinguishes day from night. Its surfaces feature handcrafted Zaratsu polishing with a distortion-free mirror finish.

It is equipped with the Japanese Caliber 5760 featuring Tough Movement 2 technology, Tough Solar charging, and dual time synchronization: atomic radio wave reception (Multiband 6) and Bluetooth connectivity via the CASIO WATCHES app. It incorporates the Time Zone Navigator function: at the push of a button, the second hand points to the city where it is midnight, allowing you to align the 24-hour ceramic bezel to quickly read the time in different time zones around the world. It features a sapphire crystal with anti-reflective coating on both sides and is water-resistant to 100 meters (10 ATM).

• Hardened Titanium, Ceramic, and Zaratsu Polishing: The titanium carbide coating and ceramic bezel protect the watch from scratches caused by everyday use (such as contact with tables, keys, or zippers), keeping its luster intact.
• Ultra-Lightweight and Hypoallergenic (99 g): Made entirely of solid titanium, it weighs nearly half as much as an equivalent steel watch and is suitable for sensitive skin.
• Sapphire Crystal with Double Anti-Reflective Coating: The optical treatment on both sides eliminates 99% of light reflections for a clear view of its green dial in any lighting.
• Absolute Accuracy with No Maintenance (Solar + Radio + Bluetooth): It charges from any light source and automatically adjusts the time and day-light saving time changes via both radio frequency and mobile phone.
• Sliding Micro-Adjustment Clasp: Allows you to instantly adjust the bracelet length by a few millimeters without tools when your wrist swells in the heat.
• Shock and Magnetic Protection: If the watch suffers an impact or passes near a magnetic field, the internal sensor detects any deviation of the hands and automatically returns them to their exact position.
