I didn't say Apple tested their IPX7 rated watch. But an IPX8 rating requires the watch be tested. Just like a jeweler has to test the watch after they replace the battery to make sure it's been assembled correctly. And that's my point. Even 1 in every 1000 of 3,000,000 watches sold will slow them down, especially if they have a failure. And if they don't test them all, they run the risk of failure with the consumer, which would be catastrophic for a brand new product launch. Then there's the issue of servicing the watch to check the seals -- clearly something Apple didn't want to worry about with this first model. So even if it could meet a higher standard, there's the added burden of labeling it as such, so Apple took the safest way to market.Why would Apple do this? I know some high end/low volume manufactures do test (usually atmospheric pressure instead of water) each case individually. Also this is usually reserved for ATM10 and higher (or is it deeper) models. It would be a huge waste of time and resources for Apple to test each
Watch, especially in a water pressure tank. Apple will just do (and does now with IPx7) what all other volume manufacture do and pull 1 of every 1000 to 10,000 to test.
