You can't buy the cellular Apple Watch in countries outside the five in which cellular will be actually available. So you can't just buy it and not use LTE, it doesn't even appear in the store.
And with the Series 2 discontinued that means and Series 1 only available in aluminum that means that in most countries you can't buy a SS watch, period.
Well technically you can, just not through Apple.
Well maybe even through Apple if you visit a country where it's available, just walk into an Apple store and there you go.
