Apple Watch shipments increased by 54 percent year after year and Apple has delivered about 2.7 million units in the third quarter of 2017. Apple's hopes in shipments were not enough to make it the best portable vendor, the title comes to Xiaomi.
Xiaomi sent about 6.9 million portable devices in the quarter, giving the company 21.5 percent market share, while Apple reached 13.1 percent market share. Fitbit trailed Apple in the number 3 track with an estimated 3.5 million portable devices sent.
Durable devices as measured by IDC include basic portable devices like simple training tracks along with smart watches like Apple Watch. Overall, the wearables market reached 32 million units in 3Q1
When it comes to Apple Watch shipments, IDC's numbers are estimated because Apple does not provide details about the number of Apple Watch models it sells. Apple Watch revenue is included in Apple's "Other" category which also includes products like AirPods, Apple TV, HomePod and more.
According to IDC, Apple Watch 4 Series, released by Apple in September at the end of the quarter, represented less than 20 percent of all Apple Watch shipments, with customers instead of the more affordable Apple Watch Series 3.
Apple was able to launch its 4-clock watch, its first watch approved for medical use, towards the end of the quarter. The new design and sizes along with the latest version of Watch OS were welcome, although the latest series represented only less than 20% of all Apple Watch shipments. The reduced price of the still-known series 3 accounted for the majority of Apple's broadcasts in the quarter.
While Apple does not share information about Apple Watch sales, during its last quarterly earnings call for the fourth quarter of 2018 (equivalent to the third quarter of the quarter), Apple CEO Tim Cook said that the company's wearables category posted revenue for September with growth over 50 percent.
