Top 5 Casio Oceanus Watches

By Chanel Lim


In a saturated market for watchmaking, Casio wanted to become one of the leading watch producers in the world — but how?


With many American watch companies focusing on accuracy and precision, Casio took on a different approach. In 1983, Casio launched the G-Shock collection — highly shock-resistant tactical watches with outstanding water-resistant features. Created by Kikuo Ibe, an engineer based in Japan, G-shock became a global phenomenon. The collection raised new standards for durability and long-lasting mechanical watches.

From then on, Casio’s continued success in technological advances has seen several innovations in watchmaking history. These include the radio-controlled solar-powered functions, compass bearings, and altitude measurements using sensor technology, among others, providing the ultimate experience for a Casio user.


Then came the Casio Oceanus — a series of watches featuring a combination of both the G-shock technology and Waveceptor’s radio time signal functions. Offering four main models, all Oceanus timepieces are worth every consideration when it comes to functionality and style.


Here are five of them.

As a limited-edition model with only 200 pieces ever produced, the Casio OCW-S5000 Super Slim High-Spec Chronograph is definitely worth coveting. Encased in an Oceanus original blue and titanium hard coating, this watch is elegant design and technology-packed.


One of the best features of this watch is its slim case. The 9.5mm thickness becomes possible because of its one-sided mounting feature. With the use of high-density technology, Casio was able to reduce the number of core components and provide a more convenient and lightweight watch for wearers. Enhanced by glowing hands and markers, the dial features a luminous layer, adding sophistication to its overall look.


In addition to its practical design, the Casio OCW-S5000 Super Slim High-Spec Chronograph offers several state-of-the-art innovations. These include an advanced time-correction system, Bluetooth and chronograph functions, a perpetual calendar (until 2100), and a power reserve indicator. What’s more, with its radio-controlled signals, you can rest assured that the time displayed is always the most accurate.
