The Apple Watch Series 8 features the same robust front crystal component as the Series 7, making it more resistant to breakage compared to earlier models.
The aluminum versions of the Apple Watch Series 8 utilize Ion-X glass to shield the display, while the stainless steel and titanium variants are protected by sapphire crystal glass. The sapphire crystal glass is a harder material than the Ion-X glass, offering superior scratch resistance. This suggests that the models with sapphire crystal are better equipped to withstand scratches and everyday wear.
Each Apple Watch Series 8 model boasts IP6X dust resistance, making it suitable for use in environments like beaches or deserts. They also have a WR50 water resistance rating, meaning they can be immersed in water up to 50 meters deep thanks to seals and adhesives. The speaker is the only point of entry, needing air to produce sound. It's been ingeniously designed to expel water using sound vibrations after coming into contact with moisture.
The Apple Watch can be used while swimming in the ocean or a pool due to its certification for immersion up to 50 meters. However, it's only appropriate for shallow water activities and should not be used for scuba diving, waterskiing, or any other activities involving high-velocity water or deep submersion. For certain aquatic sports, the Apple Watch Ultra would be an ideal choice.
Apple's Apple Watch warranty does not cover water damage, so use caution when submerging the device in water.
Bottom line
A WR50 rating indicates suitability for light swimming and bathing, but it does not cover water sports or other intensive aquatic activities. The water resistance of the Apple Watch makes it suitable for fitness enthusiasts who enjoy lap swimming. However, if you're an avid pool-goer or ocean swimmer, this may not be the water-resistant watch you're seeking.
