If you are an active scuba diver, you know that bringing technology under the water can be dangerous. However, companies like Casio are trying to beat out the pressure water places on devices by offering new technologies that can be brought into the deep – such as waterproof watches.

In this guide, we’ll talk about the best Casio dive watches by breaking them down into specific categories for every type of diver.

A Quick Look at the Casio Brand

Casio is a Japanese company founded in 1946 that is well known for their manufacturing of consumer electronic devices. Their line of products includes watches, mobile phones, calculators, projectors, digital cameras, and more.

Casio was one of the earliest manufacturers of quartz watches, which delivers a very precise frequency that keeps the watch extremely accurate. A pioneer in the watch industry, Casio was an early adapter of many advanced watch features such as multiple time zone, temperature, and GPS displays.

Today, Casio is best known for their wide range of durable, high-quality digital and analog watches – including models specifically designed for underwater divers. They offer a variety of different dive watches with unique features that will suit any kind of diver.

Casio continues to act as an innovator in the watch industry, as they recently released a new line of water resistant smart watches for the everyday active user.

Casio Dive Watch Buying Guide

Below are some of the things that anyone who wants to take their watch underwater with them should look for.

This guide will help you weed out the watches that are too fragile to follow you into the depths from the one’s that will help you have an optimum and safe dive.

  • Maximum Depth – All Casio dive watches are suitable for shallow underwater activities such as swimming and snorkeling, but there are only a few of the models can dive down deep. Many of the cheaper models aren’t suitable for snorkeling, and will likely malfunction if brought below 50 meters.
  • Shock Resistance – A good dive watch should have adequate shock resistance, especially if it is being used for deep water adventuring. Not only will shock resistance help the watch withstand the pressure, it also keeps it safe in case you accidently bump it against something in the dark water.
  • Watch Band – The band is what keeps the watch securely to your wrist, and should feel comfortable at all times. Most Casio dive watches are made with a resin band, which is a flexible plastic material that is well known for its durability. Casio watches can be easily adjusted using the interlocking buckle.
  • Type of Watch – Analog watches are the most basic kind of watch, and are often much more durable under heavy pressure. However, they often lack many of the features of digital clocks, such as alarms and calendars. Digital clocks are typically easier to read, especially when paired with LED backlighting.
  • Battery Type – There are three basic types of batteries found in Casio dive watches: solar, rechargeable, and disposable. The type of battery will dictate how long the watch will run before needing to be changed or recharged.
  • Timekeeping Capabilities – All Casio dive watches are made with a quartz-regulated electronic oscillator, which provides extremely accurate timekeeping. However, not all models offer additional timekeeping capabilities such as a stopwatch or alarm setting.
  • Special Features – Some of the more advanced Casio dive watches have new technology innovations such as GPS, Bluetooth connectivity, and altimeter/barometer sensors. These features can make diving easier, and can give you peace of mind while under the water.

Casio Dive Watch Frequently Asked Questions

Why are Casio dive watches water resistant and not waterproof?

These days, it takes a lot for a product to be labeled as completely waterproof, which means it is completely impervious to water. While many Casio dive watches can withstand the high pressures of the water, it is nearly impossible to create a completely waterproof dive watch.

Can I re-seal a Casio dive watch if water gets in?

Even though Casio dive watches are water resistant, there is still a chance that the seal can break and let water in. If your Casio dive watch breaks, there is a possibility that you can reseal the watch to restore it to its original water resistant state. You can either bring the watch into a specialist, or send it in to an authorized Casio support center.

How do I replace the battery on a Casio dive watch?

Should your Casio watch battery die, you can easily replace the battery on your own. Simply remove the watch back by loosening the screws, and gently pull the dead battery out with a pair of tweezers. Full battery replacement instructions will be included in your Casio dive watch instruction manual. We recommend that you wear protective gloves when changing the battery to prevent any transfer of oil to the delicate watch parts.

Can I clean a Casio dive watch?

There is a simple way to clean your Casio dive watch using items that can be found around the house. You can start by running the Casio watch under lukewarm water with a mild soap, drying it off with a soft towel. To clean the watch face, a toothbrush or Q-tip into some warm, soapy water before gently brushing it along the watch face. Never scrub or press down hard.
