"Water-resistant" refers to the ability of a material or product to resist the penetration of water to some degree. This means that while it can withstand exposure to moisture, it is not completely waterproof. Common examples include watches, clothing, and electronics designed to protect against light rain or splashes. The level of water resistance is often measured using a rating system, such as the IP (Ingress Protection) rating or ATM (atmospheres) for watches. These ratings indicate how well a product can handle water exposure, helping consumers choose items suitable for their activities, like swimming or outdoor sports.
