Made in Japan, this Japanese domestic market model features a black dial with signature OCEANUS blue accents, Tough Solar charging and a dual-curved sapphire crystal.\n\u003c\/p\u003e\n\n\u003ch3\u003eBlack Dial with Signature Blue Accents\u003c\/h3\u003e\n\n\u003cp\u003e\nThe sporty black-and-blue design gives the OCW-S100-1AJF a distinctive OCEANUS appearance while maintaining the simplicity of a three-hand watch. Silver-tone hands and hour markers contrast with the black dial, and a date window provides everyday practicality. Neobrite luminous elements help with reading the time in low light after exposure to light.\n\u003c\/p\u003e\n\n\u003ch3\u003eLightweight Titanium and Refined Finishing\u003c\/h3\u003e\n\n\u003cp\u003e\nThe titanium case and solid-link titanium bracelet keep the total weight to approximately 90 g. Titanium carbide surface treatment complements the lightweight construction, while Zaratsu polishing contributes to the refined exterior finish.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe case measures 45.7 × 41.5 × 10.5 mm. A dual-curved sapphire crystal with an inner anti-reflective coating combines an elegant profile with clear dial visibility. The bracelet closes with a three-fold clasp featuring push-button release.\n\u003c\/p\u003e\n\n\u003ch3\u003eTough Solar and Multiband 6\u003c\/h3\u003e\n\n\u003cp\u003e\nTough Solar converts sunlight and artificial light into energy to recharge the internal battery. Multiband 6 supports time calibration signals transmitted from Japan, the United States, the United Kingdom, Germany and China. Automatic and manual signal reception help maintain accurate timekeeping in supported areas.\n\u003c\/p\u003e\n\n\u003cp\u003e\nRadio reception depends on your location, surroundings and home city setting. When time calibration signals cannot be received, the watch operates with an average accuracy of ±15 seconds per month.\n\u003c\/p\u003e\n\n\u003cp\u003e\nAfter a full charge, the watch operates for approximately seven months without further light exposure under the specified usage conditions, or approximately 29 months under the specified power-saving conditions.\n\u003c\/p\u003e\n\n\u003ch3\u003eSmart Access World Time Operation\u003c\/h3\u003e\n\n\u003cp\u003e\nThe Smart Access electronic crown system lets you select world time through pull-and-turn crown operation. The watch supports 29 cities across 29 time zones plus UTC, with automatic daylight saving time settings. Independently driven hour, minute and second hands and date display allow the watch to adjust efficiently when changing cities, including changes that cross the date boundary.\n\u003c\/p\u003e\n\n\u003cp\u003e\nAutomatic hand position correction, a full auto-calendar, a low-battery warning and power saving add everyday convenience. This model operates independently and does not require a smartphone app or Bluetooth connection.\n\u003c\/p\u003e\n\n\u003ch3\u003eMade in Japan — Japanese Domestic Market Model\u003c\/h3\u003e\n\n\u003cp\u003e\nOCW-S100-1AJF is the Japanese domestic market reference for this black-dial titanium model.
