Summer is just around the corner, and one thing we often do at this time of year is get our watches wet and submerged. Today we'll share some tips so you can do just that and enjoy your watch this summer with the peace of mind that it will withstand whatever you throw at it.
First of all, and although it's a well-known topic in forums, blogs, and elsewhere, it's worth reiterating what we mean by water resistance . There's a bit of confusion when we talk about "water resistant," the number of atmospheres, or how many meters my watch is submersible to.
We must keep in mind that a watch rated at 1 ATM (atmosphere) of pressure, equivalent to a depth of 10 meters, does not mean that the watch tested at 1 ATM can actually withstand a depth of 10 meters. For example, the pressure a watch can withstand on the wrist of a person swimming in a pool may be greater than 1 ATM. Similarly, a watch's ability to withstand a continuous pressure of 10 ATM is not the same as a sudden pressure of 20 ATM.
After this introduction, if the watch's water resistance allows it (something you can check in tables included in the manuals), these will give you an idea of what you can and cannot do with your watch. Here's an example of a table you can find in Casio manuals:

As I mentioned earlier regarding water resistance and these tables, the meaning of resistance to immersion in the case of most common watches is controlled by the ISO 2281 standard, and in the case of diving watches, it is governed by the ISO 6425 standard. These standards determine the watch's resistance by performing a factory test under static pressure, from which a classification by levels is obtained; this figure in atmospheres, or meters, has an equivalent, which, although not "official", helps us to prevent and use our watch according to its capabilities, preserving its water resistance.
Additionally, it's always advisable to keep a few things in mind to avoid problems with your watch and prevent it from getting filled with water inside:
- Make sure the crown is always tightly closed and doesn't wobble when touched.
- Check if the glass has any cracks or chips, as this could be an entry point.
- Except in very specific models, do not manipulate pushers or the crown underwater.
- If you submerge your watch in salt water, after using it, wash it with tap water as it is not good for your watch and can damage the case and strap.
These are just a few tips, and we'll continue to expand on this information about water-resistant watches. If you have any questions or concerns, please contact us, and we'll help you so you can enjoy your watch. At Cardell Watches, we also have a workshop where we perform these checks, so if you're going to get your watch wet and aren't sure if it's water-resistant, we can help.
