You see more apple watches than other because it's one of the smart watches that can't be mistaken for a normal watch.

I see quite a lot of people using smart watches due to actively going to gym (where a lot of people use them for fitness tracking etc).

A lot of them are hard to recognise as smart watch unless you know the specific model already, or catch someone interacting with it. The ones I and my partner uses are similarly "invisible" (Garmin Fenix series).

In comparison, Apple Watch is the kind where it's immediately obvious you see an apple watch or something that apes its design.
