A watch with a water resistance of 30 meters is suitable for normal daily use, but the designation can be misleading. A rating of 30 meters does not mean you can dive 30 meters deep with the watch. Water resistance is tested under standardized conditions and does not imply that the watch is usable at that depth under all circumstances.
30-meter water-resistant watches are primarily designed to withstand splashes, rain, and daily contact with water. For swimming or diving, you need a watch with a higher water resistance.
What does 30 meters water resistant mean?
On a watch, 30 meters can be indicated as 30M, 3 ATM, or 3 BAR. These values refer to the pressure the watch is exposed to during a test.
In practice, 30 meters water resistance is therefore different from "being able to swim 30 meters deep." Movement in water, temperature differences, and pressure changes can increase the stress on the watch.
If you want a watch for swimming, look for models with a higher classification. Our collection of water-resistant watches offers more options for this.
What can you use a 30M watch for?
A 30M watch is a practical choice for daily use. Rain, a splash of water while washing hands, or an unexpected downpour typically pose no problem when the watch is properly maintained and sealed.
However, for swimming, snorkeling, or diving, a 30M watch is not the right choice. Those who regularly enter the water should consider a dive watch or a model with higher water resistance.
Even with a water-resistant watch, caution remains important. For example, check that the crown is fully closed before the watch comes into contact with water.
Water Resistance and Daily Maintenance
The water resistance of a watch is not necessarily permanent. Seals can age over time, reducing their protection against water.
Therefore, it is advisable to have the water resistance checked periodically for watches that regularly come into contact with water. Especially when the battery or the watch itself has been opened, checking the seals is wise.
A damaged crystal, a loose crown, or a case that has sustained a hard impact can also affect water resistance.
30 meters, 50 meters, or 100 meters?
The difference between these classifications is particularly important when you want to use the watch under various conditions. 30 meters is suitable for daily use and splashes. A higher classification offers more possibilities, but still does not automatically mean you can use the watch for every water sport.
Those looking for a watch for an active lifestyle should therefore determine in advance what it will be used for. For daily use, 30M may suffice; for swimming or water sports, a higher water resistance is more sensible.

Buying a 30-meter water-resistant watch
A 30-meter water-resistant watch is primarily suitable for those looking for a watch that can withstand the normal conditions of a day. It offers practical protection against splashes and rain, but it is not a classification for swimming or diving.
At Juwelier Van de Heyning, you will find water-resistant watches for various styles and uses. Check the specifications of each model before making a choice, so that the water resistance matches the intended use of the watch.
