What Is Illuminator In Casio Watches?

The illuminator is a signature feature of the Casio Illuminator watch.

It is a lighting panel that lights up the entire display for easier reading in low-light conditions, which helps improve visibility so users can conveniently tell the time in the dim lights.

There are 2 styles of illumination for Casio watches:

  • An electroluminescent (EL) panel under the dial generates gentle, uniform green light. The light is not very bright, but it helps you see things like hands and hour markers. 

  • Super light or a high-intensity LED illuminates the watch dial to significantly improve visibility in the darkness. The bright white light exudes from one or two LEDs attached to the chapter ring.

Different models of the watch have different ways to turn on/off the illuminator, either with a push of a button or by tilting the wearer’s wrist.

Once turned on, the light can stay on for 1.5 or 3 seconds, depending on the chosen illumination duration setting. 

How does Illuminator In Casio Watches work?

The illuminator in Casio watches uses a special type of LED (light-emitting diode) to produce a bright light.

This light is then directed towards the watch's dial, making it easier to read in low-light conditions.

You can activate the illuminator by pressing a button on the side of the watch or by tilting the watch towards your face.

The light will stay on for a few seconds before turning off automatically.

What are the benefits of using an illuminator?

The main benefit of using an illuminator is that it makes it easier to read your watch in low-light conditions.

This can be particularly useful if you need to check the time at night or in a dark room.

The illuminator can also be used to help you find your way in the dark, as it will light up the path ahead of you.

EL Vs. LED Illumination

LEDs are preferably used to illuminate new Casio models, while blue-green electroluminescent backlight can be only found in older watches.

LED lights, from a technical point of view, outcompete EL panels in two ways.

Battery

EL panels require significantly more power to operate than LEDs.

As a result, continuous use of the EL backlight can quickly drain the watch battery.

Simple Implementation

EL panels are a layer of powder zinc sulfide with copper, which requires high-voltage electricity. 

Meanwhile, a Casio operates at a very low voltage, so this difference necessitates the setup of the power converter to get to the high voltage for EL panels to glow.

This converter is inexpensive but rather bulky and consumes a lot of power.  

LEDs are way simpler to incorporate into a watch.

They glow at regular voltage without any converter needed.

However, many users prefer EL panels over LEDs because they are easier on their eyes.

In addition, the lights they produce are even through the entire dial.

LEDs, on the other hand, are positioned at one or two corners of the display.

They give uneven illumination since the corners seem brighter than other areas. 

How Do I Set The Time On A Casio Illuminator Watch?

  1. Press down the Mode button at the bottom left of the watch to display the currently set time.
  2. Hold down the Adjust button right above the Mode button until the digital time starts flashing.
