Will Apple be the smartwatch saviour?

The lack of detail about sales has led some to declare the Apple Watch a flop, but its launch has focused attention on the broader smartwatch sector

Three months after launching its first smartwatch, Apple has reported record revenues and vast iPhone sales - but no numbers on its new wearable. That has got commentators asking whether the Apple Watch is a flop.

Before its launch, financial analysts were predicting watches would fly off the shelves to the tune of 40m in the first year. Those estimates were based on the performance of Apple's iPhone, which sold 47.5m in a single quarter.
