If, for some reason, you want to find out which iPhone model a person owns but don’t want to ask them, you have to look no further than their wrist.
It’s possible to get your Apple Watch up and running using someone else iPhone, but most people are unlikely to go for this option. So, it’s reasonable to assume that most Apple Watch owners also own an iPhone.
The iPhone 13 and 13 mini were the most popular iPhones among those who didn’t have an Apple Watch, owned by 31 percent of them. Only 15 percent of non-smartwatch owners bought the iPhone 13 Pro or iPhone 14 Pro phones.
The base iPhone 14 Pro model costs $999 and it’s understandable that someone spending this much on a phone wouldn’t hesitate to buy an Apple Watch.
It makes sense that Apple customers who invest in an Apple Watch are more likely, and perhaps more able, to invest in a premium iPhone. Apple Watch owners are more dedicated to the Apple ecosystem overall, so they see value in owning the most advanced iPhone models to complement their Apple Watch.” -CIRP
