Sales of the Apple Watch have fallen by 71pc, with the company claiming a shrinking share of the market for wearable technology.
Apple sold 1.1 million of the devices in the third quarter of the year, down from 3.9 million a year ago, according to research company IDC.
Tim Cook, the company's chief executive, countered that the Apple Watch is set for its highest-ever sales in the current quarter, following the release of a new model in September. He said that sales to consumers had been at record levels in the first week of October, and that growth was "off the charts".
The Apple Watch, the company's first new product launched under Cook's leadership, has had muted sales since it was first released last year. IDC said the decline in sales was down to "an aging lineup and an unintuitive user interface", as well as the wait for a new model holding back consumers.
In September, Mr Cook unveiled the "Series 2" version of the device, which is waterproof, features a GPS chip and has a more powerful processor, as well as a revamp of the Apple Watch operating system.
