This is the fourth iteration of the hugely successful Apple Watch Series first launched in 2015. Apple (for once) have listened to customer feedback regarding failings on the previous models, and the Series 4 sees a marked improvement in interface design, battery life, and fitness tracking.

It’s the largest screen of an Apple Watch yet and comes in two choices of size. The larger 44mm size offers a surprisingly detailed and responsive touchscreen that dovetails beautifully with a simple and intuitive interface design.
