The Apple Watch is one of Apple's most successful first-generation products, according to Apple CEO Tim Cook. Cook says the device sold faster than the original iPhone or iPad and he also said that sales were highest last month, dismissing reports about a significant drop in demand.

No real sales numbers for the Apple Watch were provided by Apple and Cook's statements have only left people with more questions. The best data we have on the Apple Watch comes from third-party sources like Slice Intelligence. For its part, Slice Intelligence reported Apple had sold 2.79 million Apple Watch units since April.

As usual, Apple did not keep up with the demand for its first wearable.

The Apple Watch is part of Apple's "Other Products" category in its financial report and that category has seen a 49% increase in revenue over last year.
