The WR50 is a type of water-resistant watch designed to withstand water pressure up to 50 meters. This means it can handle splashes, rain, and brief immersion in water, making it suitable for everyday wear. However, it is not recommended for swimming or diving. Watches with a WR50 rating often feature durable materials and are popular among casual users who want a reliable timepiece. Brands like Casio and Seiko offer models with this rating, appealing to those who appreciate both style and functionality in their accessories.
