Features of Casio Oceanus Watches

Each Casio Oceanus watch has these key characteristics.

1. Analogue dial

Despite having so many advanced features, Casio decided to keep the traditional analogue dial for their watches. Earlier models have a combined analogue and digital watch face. However, the current models strictly have an analogue dial only.

2. Five-motor drive

The Casio Oceanus watches consist of five internal motors that run independently. These motors control the time, stopwatch, day and date functions of the watch, among others.

3. Multi band

Oceanus models boast the multi band feature. Simply put, it is a radio technology that fetches signals from key locations around the world. These signals will help adjust the time on the watch, depending on the location.

These key locations are the Japanese time signal (JJY), China in Shangqiu City, the American time signal (WWVB) from Colorado, and the European time signals from both England (Time from NPL (MSF)), Germany (DCF77).

4. Sapphire crystal

There is no denying that Casio’s Oceanus collection boasts top-notch technology. And to fully maximise their watches’ features, Casio equipped their models with sapphire crystals.

Indeed, a sapphire crystal is one of the hardest crystals available. Consequently, this makes the watch extra resistant to scratches. For reference, sapphire has a rank of 9 under the Mohs scale of hardness. This means that it can handle a lot of stress that you put it through. And apart from being resistant to scratches, it is also shatter-resistant. This is the reason why a lot of luxury watches use sapphire crystals to protect their dials.

5. GPS

The key locations mentioned for the multi band feature are limited. But you don’t need to worry about that. Casio Oceanus watches also have a built-in GPS. This added feature allows the watch to auto-synchronise the time anywhere in the world. Apart from that, the GPS adds accuracy.
