announced the new Apple Watch Series 7 in September, the company highlighted the new smartwatch's improved durability. As well as what Apple promises is a more crack-resistant front crystal, it also pointed out that the Series 7 is rated IP6X, meaning that it's certified dust-tight.
The Series 7 is also water resistant, just like Apple's previous watches, with a WR50 rating. Rather than let these claims go unexamined, I decided to conduct a couple of experiments to see if these durability ratings were legit.
I went online and found advice on creating two different apparatuses: one for water and one for dust (or in my case, flour).
The water chamber allowed me to apply enough pressure to approximate the conditions at a depth of 50 meters. Apple doesn't say the watch is rated for 50 meters under water -- the WR50 rating means it's fine for swimming and splashing around, not prolonged submersion.
That didn't stop me from trying it, though.
I also put together a vacuum chamber so I could introduce the watch to a dusty environment with the ambient air pressure removed.
Neither of these experiments are truly scientific tests. They are just meant to demonstrate how the Series 7's water and dust resistance might hold up in the real world.
How did the watch perform? Take a look at the embedded video to find out.
