Casio Oceanus Cachalot OCW-P3000-2AJF JDM Titanium and Ceramic Watch (42.9 mm, Solar-Powered, Multiband 6 Radio-Controlled, Bluetooth, Double AR-Coated Sapphire Crystal, Zaratsu Polishing, Made in Japan)

Description and Key Features

The Casio Oceanus Cachalot OCW-P3000-2AJF is a high-tech timepiece exclusively available in the Japanese domestic market (JDM) and assembled at the prestigious Premium Production Line in Yamagata, Japan. Designed for the global traveler and high-end everyday use, it combines the extreme lightness of solid titanium hardened with titanium carbide (weighing only 99 grams in total) with a rotating bezel featuring a two-tone ceramic insert that visually distinguishes day from night. Its surfaces feature the exclusive hand-polished Zaratsu finish, achieving a distortion-free mirror finish characteristic of Japanese luxury watchmaking.

Inside, it features Tough Movement 2 (TOUGH MVT. 2) technology with Tough Solar power and dual time-synchronization methods: atomic radio wave reception (Multiband 6) and Bluetooth® connectivity via the CASIO WATCHES app. It incorporates the innovative Time Zone Navigator function: with the press of a button, the second hand points to the city where it is midnight, allowing you to align the triangular marker on the 24-hour ceramic bezel to read the time at a glance in the world’s major time zones. All of this is protected by a sapphire crystal with anti-reflective coating on both sides and is water-resistant to 100 meters (10 ATM).

• Luxury Finishes (Titanium + Ceramic + Zaratsu Polishing): The combination of Zaratsu mirror polishing with a titanium carbide coating and a ceramic bezel prevents scratches from daily use (contact with tables, keys, or zippers) while keeping the shine intact for years.
• Ultra-Lightweight and Hypoallergenic (99 g): Made entirely of solid titanium, it weighs nearly half as much as an equivalent steel watch and does not cause allergies or skin irritation.
• Sapphire Crystal with Double Anti-Reflective Coating: The optical treatment on both sides eliminates nearly 99% of light reflections, creating the visual effect that there is no crystal over the dial.
• Absolute Accuracy and Zero Maintenance (Solar + Radio + Bluetooth): It charges from any light source (solar or artificial) and automatically adjusts the time and day-light saving time changes, either via atomic signals or by pairing with a smartphone.
• Sliding Micro-Adjustment Clasp: Allows you to instantly lengthen or shorten the bracelet by a few millimeters without tools, ideal for when your wrist swells in the heat or during long trips.
• Tough Movement 2 Protection Against Shocks and Magnetism: If the watch suffers a strong impact or passes near a powerful magnet, the internal sensor detects the deviation of the hands and automatically returns them to their exact position, down to the second.
