You left out the part that didn't support your statement.
Nickel. Apple Watch, the space gray Apple Watch Sport, the stainless steel portions of some Apple Watch bands, and the magnets in the watch and bands contain some nickel. However, they all fall below the strict nickel restrictions set by European REACh regulation. Therefore, while nickel exposure is unlikely to be a problem, you should be aware of the possibility in case you're susceptible to nickel-related reactions.
My statement about Apple being a different kind of company was in this regard. They clearly designed the product deliberately to make the level of nickel be as low as possible. Other companies may not go to the trouble.
You can say I'm wrong but it's all interpretation.
You were indeed wrong in originally doubting that they used nickel. However, some people are hypersensitive to nickel so it can still pose a problem even if present in trace amounts well below the strict nickel restrictions set by some regulation body.
