Casio WR, an abbreviation that has resonated in the world of watchmaking for decades, represents much more than simple letters on a watch dial.
This designation, derived from the English term “Water Resistant,” is a testament to Casio’s commitment to durability, as it ensures that the watch will remain waterproof in the face of any adversity.
However, not all WR watches have the same water resistance, nor are they designed to withstand the same conditions, so some models are better than others depending on their intended use.
In this post, we will delve deep into the WR concept and showcase some of the best Casio WR watches, organizing them based on their water resistance and features.

✚ What Does Casio WR Mean?
The abbreviation “WR” on Casio WR watches stands for “Water Resistant.” This feature indicates that the watch has been designed to withstand the entry of water up to a certain degree.

However, it is crucial to understand that “water-resistant” does not necessarily mean that the watch is completely waterproof, especially if the meters it can be submerged to are not specified.
Casio WR watches adhere to the ISO 2281 standard, also known as DIN 8310, which clearly specifies the tests that watches must undergo to determine their water resistance.
These tests subject the watches to different atmospheric pressures to simulate water pressure but are not conducted under real immersion conditions.
For example, the pressure equivalent to 100 meters underwater is 10 bars (BAR), but this does not necessarily mean that a Casio WR 100M watch or any other with this specification can withstand that depth.
In real conditions, the dynamic pressure generated by movement in the water can exceed the static pressure used during the tests, and other factors such as the watch’s condition or ambient temperature can come into play.
That said, Casio establishes a standard rating to clearly define what can and cannot be done with its WR watches, considering the inscriptions on their backs:
| Marking on the back of the case | Splashes, rain, etc. | Hand washing, showering, etc. | Swimming and snorkeling | Diving with immersion |
|---|---|---|---|---|
| Not indicated | No | No | No | No |
| WR or WR 3BAR | Yes | No | No | No |
| WR 5BAR | Yes | Yes | No | No |
| WR10BAR | Yes | Yes | Yes | No |
| WR 20BAR | Yes | Yes | Yes | Yes |
➤ Casio WR30M / 3BAR
The watch has been subjected to a pressure equivalent to 3 bars, which is equal to a column of water with a height of 100 meters applied to 1 cm². It is suitable for daily use and resistant to splashes but is not recommended for bathing or swimming with it.
➤ Casio WR50M / 5BAR
The watch has been subjected to a pressure equivalent to 5 bars, which is equal to a column of water with a height of 50 meters applied to 1 cm². It is suitable for swimming but not for diving or high-intensity water activities.
➤ Casio WR100M / 10BAR
The watch has been subjected to a pressure equivalent to 10 bars, which is equal to a column of water with a height of 100 meters applied to 1 cm². It is suitable for swimming and shallow diving but not for scuba diving.
➤ Casio WR200M / 20BAR
The watch has been subjected to a pressure equivalent to 20 bars, which is equal to a column of water with a height of 200 meters applied to 1 cm². Designed for water sports and deep-sea diving.
