In the keynote on September 7, Apple introduced, in addition to the 7 iPhone and iPhone 7 Plus, second-generation Apple Watch and a review of the first generation whose novelty was the new processor SP1. Apple Watch Series 2 has inherited the price of the previous model, while the 1 Series has dropped its price. Even with the release of Series 2 and the discount on the 1 Series, the analyst Ming-Chi Kuo, the most famous in the Apple world, ensures that the Apple Watch sales have fallen by 15-25% with respect to 2015.
According to Kuo, there are 4 reasons why Apple has not managed to attract the attention of potential clients: there is no distinctive application of great importance, poor autonomy, dependence on the iPhone and multi-touch experience offered in a device wearable or wearable. Although personally I also think that there are other more logical reason.
Many of those who wanted an Apple Watch already had it
Apple Watch Series 2 has arrived with the main novelties of the GPS, the S2 processor and the water resistance 50 m (which are 50 meters). If we take into account that the clock should be a device that did not change as often as the mobile, we think that many of the users who wanted the Apple Watch bought it sometime after April of 2015. In 2016, that these users have done is not to renew a device that satisfies them.

According to Kuo, Apple has lowered the price of the 1 Series will not sales to increase, which, in my opinion, gives more strength to the argument that many of those who they wanted to because they had it.
Presented as his “most personal device,” Apple Watch will not be renewed, or shouldn’t, every year, and this is something that users also have clear. The changes that will come with each model will not be as important as the iPhone, and that neither will invite us to change. That is what it seems you passed this year and something that could have changed if they had included support for 3 G connections, something that looks like that Tim Cook and company valued but dismissed due to problems of autonomy.
Until Apple does not give official data, we cannot know how many Apple Watch sold by 2015 and many in 2016, but Kuo says that this year will be sold from 8.5 to 9 million units, down from 10.4 million units last year. Looking at the good side, perhaps this serves to be motivating and launch in 2018 Apple Watch with major changes. You see?
