It is Seiko? Rolex? No! It is the Apple Watch, which has now become the fast top-selling timepiece in the world. As Apple Watch Series 3 has become official just a few hours ago, Apple CEO Tim Cook has also revealed in the flagship event today that Apple Watch is the best-selling watch in the world.

The first-ever Apple Watch was released on April 25, 2015, and it ranked on second number after only Rolex to become the top-selling watch in second quarter of 2016. By that quarter, Apple Watch sales had already surpassed the other top-selling watches such as Casio, Patek Philippe, Omega, Fossil and Seiko.

Moreover, Apple Watch has also become the widely used heart monitor around the world as well. The latest features added in Apple Watch Series 3 will only enhance Apple’s reputation in smartwatch business and sales, and it will only help Apple compete with the different brands around the world.
