Watches are an essential part of our daily lives, and many of us rely on them to keep us on time and organized. But what if you want to take your watch with you for a swim, forget to take it out when showering or wear it in the rain? It's important to know whether your watch is waterproof or not. In this blog, we'll explore the ways to determine if your watch is waterproof.


Most watches come with information about their water resistance, which is usually indicated by a number on the back of the watch or in the instruction manual. The most common marks are:

Water resistance: Your watch can withstand accidental splashes for example rain, but it’s not suitable to be submerged into water, nor suitable for shower.

3ATM: Your watch can withstand accidental splashes, such as rain or when washing your hands, but is not recommended to use it in the shower.  

5ATM: This type of watches, like our Chronometer Watch, can withstand splashes, and can be worn in the shower but you should not swim with it. 

10ATM: Your watch is suitable for the shower, swimming, snorkeling but not suitable for high board diving or aqua diving. If you are interested in a 10ATM watch check our Heritage Watch.

20ATM: Your watch is suitable for swimming, high-impact water sports and scuba diving.

30ATM: Suitable for all high-impact water sports, scuba-diving and saturation diving.

However, if you can't find this information, there are a few things you can do to determine if your watch is waterproof.

Check the Instruction Manual: If the water-resistance mark is not present on the watch, check the instruction manual for more information. The manual will usually indicate the level of water resistance, as well as any restrictions or limitations.

Check the Crown: If the watch has a screw-down crown, it is more likely to be water-resistant than a watch with a push-pull crown. The screw-down crown creates a tighter seal, which helps to keep water out.

Have it Tested: If you're still unsure about the water resistance of your watch, you can have it tested by a professional. This can be done at a watch repair shop or a jewelry store.


Even if your watch is water resistant here are two things that you need to pay attention in order to preserve the water resistant seal that can get damage over time:

Check the status of the seal: The seal is the main barrier that prevents water from entering the watch. If the seal is damaged or worn, it is likely that water will enter the watch, even if it has an appropriate water resistance rating. Therefore, it is important to regularly check the status of the seal and replace it when necessary.

Avoid exposing the watch to sudden temperature changes: Sudden temperature changes can affect the watch's seal and cause water to enter. Therefore, it is important to avoid exposing the watch to sudden temperature changes, such as entering a hot tub or going out on a cold day after being in a warm environment.


Are you having trouble finding a good watch with water resistance? 

Here at Dicci we have many watches, from 5ATM to 10ATM, with different styles to meet your personal preferences.




It's important to note that the water resistance of a watch can decrease over time due to wear and tear, exposure to moisture, and other factors. To ensure that your watch remains water-resistant, it is recommended to have it tested regularly and to avoid exposing it to extreme temperatures and harsh chemicals.

In conclusion, knowing whether your watch is waterproof or not and what type of water mark it has is important so you can find the watch that best suits your lifestyle.
