To commemorate the 20th anniversary of OCEANUS, this limited edition model expresses the scenery of sailing through a colorful ocean, and likens the story of "blue" that OCEANUS has been weaving since its birth in 2004 to the determination to continue taking on challenges in the future.
The OCEANUS Manta line pursues high-quality finishes and a thin, beautiful form.
The OCW-S400SG-2AJR, which commemorates the brand's 20th anniversary, is a compact three-hand model in light blue.
The sapphire glass on the bezel is coated with a light blue color for the first time in the brand's history, giving the watch a vibrant look.
While retaining the attention to detail that is unique to the flagship line, such as sapphire glass with double-sided anti-reflective coating, a titanium case with Zaratsu polishing, and a high-quality finish for the band, the watch has a simple three-hand design with hour, minute, and second hands, achieving beauty and high visibility.
This model commemorating the 20th anniversary of OCEANUS is limited to 700 pieces worldwide, and comes with a special box as a special specification unique to the limited model, and the words "20th Anniversary" are inscribed on the back cover as proof of the limited model.
