This is a really impressive upgrade from Apple – if you're thinking of getting yourself a Watch from the brand, we'd suggest you start thinking about this one. Given that the display is the only real upgrade, you could say there's not much of a change; but it really makes a difference, and the smart health stuff is going to make this more attractive to those who take a keen interest in their wellbeing.

The Apple Watch Series 4 comes in two sizes — 40mm and 44mm – and also brings along a 30 percent larger display. There’s also a redesigned modular watch face with more detailed and graphic information. Users can see stocks and heart rate, track scores from sports teams, view boarding information, and more. In terms of colors, the Series 4 comes in three aluminum finishes — silver, gold, and space gray. The Series 4 also comes in gold stainless steel with a Milanese band, in addition to the silver and space black stainless steel options. The new bands will also work with any of the Apple Watch predecessors.
