In their latest report on wearables, IDC has indicated that Apple shipped just over 4 million Apple Watch units in the third quarter of 2018. It represents a 54% growth over the same quarter in 2017 and was largely driven by the Series 3 watch.
In total, IDC estimates that 4.2 million Apple Watch models were shipped in the quarter. That is compared to 2.7 million in 2018. The jump in shipments moved Apple to 13.1% of the overall marketshare, up from 10.3% for the same quarter in 2017. That said, Apple still does not lead in the overall marketshare. That goes to Xiaomi which holds 21.5% of the market.
As for which Apple Watch model sold the best, IDC estimates that it was the Series 3. In their report, they estimate that the new Series 4 accounted for about 20% of Apple’s sales. This is largely due to the release of the Series 4 in September, the middle of the quarter in question. IDC calls out that the reduced price of the Series 3 also contributed to the lopsided sales estimates.
Digging further into the report, the big loser in the third quarter of 2018 was Fitbit. The company saw a 3.1% drop in growth and saw their marketshare drop from 13.7% to 10.9% year-over-year.
