Casio 【Genuine】 CASIO Oceanus Manta S400 Series OCEANUS 20TH ANNIVERSARY 700 limited editions OCW-S400SG-2AJR Description

To commemorate the 20th anniversary of OCEANUS, this is a limited edition model that expresses the story of "blue" that OCEANUS has been weaving since its birth in 2004.
From the "OCEANUS Manta" line, which pursues high-quality finishes and a thin, beautiful form, comes a compact three-hand model with a vivid light blue color.
While retaining the attention to detail you expect from a 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, this watch has a simple three-hand design with hour, minute, and second hands, achieving beauty and high visibility.
Limited to 700 units in Japan, it comes with a special box and has the words "20th Anniversary" inscribed on the back cover.

About waterproof function

Water resistance is effective for watches with a pressure of less than 5 atm in daily life, but the packing that plays the role of water resistance requires caution against excessive use of detergents. A watch with a water resistance of 10 to 20 bar or less is suitable for water sports, but for leisure such as scuba diving, we recommend a watch with a water resistance of 100 m. Models manufactured before 2000, such as antiques, may not maintain their waterproof function due to various reasons such as deterioration over time. Even if it is a waterproof watch for 200m, please be careful when using it in a wet place.
