If you’ve been reading up on Swiss watches, then you’ve probably encountered the term “water resistance” a lot of times. So what does this mean exactly? In essence, the International Organization for Standardization refers to it as the capability to withstand water that enters the case.
In the case of Swiss watches, “water resistance” is used as the more appropriate term as opposed to “waterproof.” But since the guidelines are still quite vague, we’ll give you further details on what you can expect from a water resistant watch:
Water resistance of up to 50 meters – it is wearable for sports and can withstand light rain. However, it is not advisable to wear it around water (swimming, submerging it on household sink, etc.)
Water resistance of up to 100 meters – it can be worn while taking showers. It is also suitable for surfing, snorkeling, swimming, and even poolside diving (depending on the make). Major brands such as Omega, Tissot, and Rolex produce top-quality pieces with aquatic orientation. They have a strong reputation for water resistant watches.
Water resistance of up to 300 meters – this feature makes the watch suitable for scuba diving but only at depths that do not require helium gas. With that being said, manufacturers recommend that the diving watch pressure should be tested every two to three years.
