How to Use a Dive Watch?

Dive Watch

Are you wondering how a dive watch works?

This post will discuss how to use a dive watch and directly guide you in understanding the usefulness and the factors you need to consider before diving underwater.

But, before going further into a more extensive discussion, let us know first what a dive watch is.

A diving watch or a dive watch designed intended for diving, for diver’s safety underwater and worked as a time indicator to every diver who used it when underwater. A diver watch has a feature of water resistance higher than 1.0 MPa, which is equivalent to 330 ft. A regular dive watch has a capacity water-resistance of approximately 200 to 300 m for 660 to 980 ft. A modern dive watch has more exceptional features than the typical one.

Also, every diver must be aware of its parts. Typically dive watches have five primary parts:

  • Case- holds the inner working parts of the watch. It serves as the protection of the mechanisms inside. See to it that the case can firmly hold the water pressure, up to 300 meters deep, and it is an ISO certified.
  • Lugs- where the case of the watch attaches to the strap.
  • Bezel- works as the rotating function, a significant feature for safety when diving underwater, and comes with a self-winding drive. Bezel used as an indicator of the term of time when you are underwater.
  • Dial- dive watches provided with three dials. It is another safety feature as it makes it easier for the user to see the dials underwater.
  • Strap-usually constructed from rubber or stainless-steel metals, which created from leather materials with stainless steel hardware.

How to Use a Dive Watch: Important Factors to Consider

A dive watch is a necessary tool for any diver. A modern dive watch can tell time and do fantastic work like providing vital information to divers how deep is the water, temperature, and measuring, how long a diver can stay underwater.

Choose a dive watch that has a high water pressure resistance

When buying a dive watch, make sure you choose a dive watch that has high water pressure resistance, and will not rust easily.
It is very vital to know how to use a dive watch, before using it underwater. Every dive watch built specifically, with different features, and it is very important to know the functions, and uses, before taking it underwater.

Know the capacity and control of a dive watch.
Does your dive watch meant for the deep of water you want to dive?
There’s a saying that goes, “Safety first before pleasure.”
Know the entire features when purchasing a dive watch. Companies are not exposing the disadvantages of an item so, you require to know the resistance and capacity of a dive watch underwater, before taking it deeper.

Set your dive watch first, before taking it underwater

It is very important to set your dive watch before using it underwater. Setting the bezel into how many minutes you want to stay underwater is very vital.

Learn how the bezel works

Its function is to indicate time or minutes a diver and to monitor the diver’s time spent underwater. Oxygen has a moderate capacity, the bezel can notify, and remind a diver, to secure from exceeding the time limit. If the bezel accidentally touched, it changes the time you previously set, before diving underwater.

Let say if a diver has a time limit of 25 minutes, subtract the number 25 from 60 minutes (60 – 25 = 35), to get the difference.

If you set it to zero, you’ll recognize the time has passed by meaning, it helps a diver to know the duration of time he stays underwater, which is very helpful.

Choose a dive watch that is an ISO certified.

A diver’s watch must be by its standard with ISO 645, meaning it passed with the ISO standard tests. It is suitable for diving and has an underwater resistance of 100 m (330 ft) or deeper. Dive Watches with no ISO 6425 signs, not meant for scuba diving.


Knowing the different features of a dive watch is very significant, its uses as well. A dive watch meant for diver’s safety, and its condition affects how it performs. So, it is highly advised to take care and learn how to use a dive watch accordingly for your safety.
