     Description (2,840 characters)
OCEANUS, which pursues high-quality finishes and multi-functionality with the brand concept of "Elegance, Technology", introduces a collection designed with a classic style theme that radiates timeless appeal.

The dial has a semi-matte gradation finish and is colored in three layers: silver vapor deposition, color painting, and gradation pattern printing on a dial formed using a newly developed mold.

From the center to the periphery, the colors and light blend together in a subtle way, creating a rich expression.

By precisely controlling the transmittance while ensuring the amount of light required for solar charging, we have made it possible to produce a dial with vivid color.

The bezel ring is made of sapphire glass.

The top surface is laser-processed to create a semi-matte finish.

The material has a unique glossy finish, like frost on the surface, and the soft light it captures brings out the expressive colors of the bezel.

The OCEANUS Manta line-up, which pursues a high-quality slim style, includes the chronograph OCW-S7000RA, the three-hand analog OCW-S400RA, and the Classic Line line-up includes the solid-design OCW-T2600RA
