I think you're stretching a bit in terms of it's looks and it's obvious you don't know what you're talking about. The Apple Watch doesn't need the aid of the iPhone to work the standard functions. You can go the whole day using it and leaving your iPhone at home.
I can also buy an iPhone and use it without the sim.
The apple watch needs an iPhone for full functionality , stop pretending otherwise !
The poster knows better than you that an iPhone is necessary if you intend to use it for more than a watch and a few basic functions!
