What is wr-50?

WR-50, also known as Weather Resistant-50, is a waterproofing rating standard used for electronic devices. It is a common rating for water-resistant watches, fitness trackers, and smartphones. The rating indicates that the device can withstand exposure to rain, moisture, and splashes without being damaged. It does not guarantee that the device can be submerged in water or that it will remain operational in extreme weather conditions. WR-50 is equivalent to an IPX7 rating, which means the device can be submerged in water up to 1 meter deep for up to 30 minutes.
