Casio Men's OCEANUS Retro Tone Collection OCW-S400RA-3AJF Watch
| Product Highlights | |
| Introducing a collection designed around the theme of timeless charm in classic style from OCEANUS, which pursues high-quality finishes and multifunctionality under the brand concept of "Elegance, Technology." The dial, finished in a half-matte gradient, is colored through a unique process involving silver deposition, color painting, and gradient pattern printing on a newly developed mold. This creates a captivating expression where colors and light blend exquisitely from the center to the periphery. By meticulously controlling light transmission to ensure the required amount for solar charging, vibrant dial colors are achieved. The bezel ring features sapphire glass with a laser-processed top surface finished in a half-matte style. It exudes a unique luster reminiscent of frosted surfaces, enhancing the bezel's color with softly captured light. The lineup includes the OCW-S7000RA chronograph and OCW-S400RA three-hand analog from the slim-styled OCEANUS Manta, as well as the OCW-T2600RA with a solid design from the Classic Line. The OCW-S7000RA and OCW-S400RA from Manta receive accurate time signals via standard radio waves and Bluetooth® for dual-way timekeeping, while the OCW-T2600RA receives standard radio waves. All models are equipped with Tough Solar technology, offering five distinct personalities to complement the wearer's daily life. | |
