Despite the fact that the Apple Watch is consistently playing second (or third) fiddle to the iPhone in terms of public attention, the evidence suggesting that Apple has yet another hit product on its hands is piling up.

According to estimates by market research firm Canalys, the Apple Watch had its best quarter ever in Q4 2017. Driven by the release of the Series 3 model including (optional) LTE support, Apple shipped 8 million watches between October and December, bringing its total for the year to more than 18 million units.

As our chart illustrates, that puts Apple ahead of the entire Swiss watch industry (think Rolex, Swatch etc.) for the quarter, supporting the company’s claims that the Apple Watch became the top-selling watch in the world some time in 2017.
