Oceanus is the elite line of Casio watches designed for both men and women. The line uses technology from both the G-Shock and Waveceptor watch series. Originally available internationally, the Oceanus line has been discontinued in the US in favor of the Casio Edifice line.


All Oceanus watches are known for the following key characteristics:

  • Analog watchface – All Oceanus watches are analog, with some earlier models having a combined analog and digital watch face.
  • Five-motor drive – present on more of the contemporary models, the five-motor drive consists of five internal motors running independently to control dials for time, stopwatch, seconds, day of week, and hours.
  • Multi-band 5 (USA) or Multi-band 6 (Japan) – perhaps the most significant aspect of the Oceanus line is the ability of all watches to automatically synchronize with the Japanese time signal (JJY), the American time signal (WWVB) from Colorado, and the European time signals from both England (Time from NPL) and Germany (DCF77). The synchronization feature does not work correctly in Arizona, which does not observe daylight savings time. The Japanese Multi-band 6 models add the Chinese time signal in Shangqiu City, China, at 68.5 kHz. Thus, the Oceanus watches will auto-synchronize themselves if one is to visit Europe, North America, Japan, or China (Multi-band 6 models). (Note: Not all American Oceanus watches carry the Multi-band 5 technology as it is relatively new. Only Models 700 and above have the Multi-band function)
  • Sapphire crystal – the watch crystal that encases the Oceanus watch is a sapphire glass, which is very scratch resistant and is found on higher-end watches.

Oceanus 600 series[edit]

The Oceanus OCW-T600 series wristwatches are the basic Oceanus model of a Japanese market. a

Oceanus CACHALOT[edit]

The Oceanus CACHALOT series wristwatches are designed imaging marine sports. Moreover, it includes the rotation bezel and the yacht timer chronograph.

Oceanus 700 series[edit]

The Oceanus ocwm700tba series watches was the last Oceanus watch model introduced in the American market. It features a complete analog face with no LCD screen as well as the standard characteristics for Oceanus watches. It also includes a tide meter to show the status of the ocean tides in the current time zone.

Oceanus 1000 Series "Manta"[edit]

Released on June 1, 2007, the Oceanus Manta is the newest in the line of Japanese Oceanus watches. Complete with the sapphire crystal and the MULTI-BAND 5 technology, the Manta is by far the most versatile and the most expensive watch out of all the Oceanus watches with a base price of 100,000 Japanese Yen (approx. $1000 American). It does not include the tide meter that appears on the 700 series. It closely resembles the 600 series watch style however thinner than both the 700 and 600 series watches.

The most significant characteristic about the Oceanus watch is that it has the world's thinnest solar-powered chronograph. The watch has a thickness of about 9.8mm.


The Oceanus line has been discontinued outside Japan and succeeded by the Casio Edifice brand.
