Apple's latest smartwatch is selling at twice the volume of the Apple Watch 2 when it was on sale last year.
That means the Apple Watch brand is growing at a steady rate, but it's not exactly clear why the new watch is selling so much better than the Apple Watch 2 did.
While the Apple Watch 3 does come with LTE integration and a barometric altimeter, that's still quite a limited upgrade considering you have to spend more on the mobile internet version of the watch.
Great news for the Apple Watch
It may be that people who want to be able to run without their phone are loving the new feature, but being able to use the LTE version is a little complicated. In the UK, it means you need to be on the EE network and pay extra every month to use the watch without your phone.
On the other hand, it could also be that word of mouth is working well for Apple's latest wearable. A lot of the kinks of the first two editions of the watch have now been worked out, and the Apple Watch 3 is the most mature version of the wearable yet.
We won't ever know for certain why the Apple Watch 3 is getting this boost, but it bodes well for the future of Apple's wearable.
In fact, wearables have started becoming a much more important category for Apple in recent months. Wearables are up 70% year-over-year for Apple – that includes AirPods and Beats headphones too – so expect to see more focus on this area of Apple's business.
Now we just have to wait and see how long it will be until we get an Apple Watch 4 announcement.
