Apple Watch shipments grew 22% in 2018, according to new Counterpoint Research data, and a large chunk of that appears to have been due to the popularity of the Series 4.

The company says that the Apple Watch Series 4 was the best-selling model during 2018 despite being available for just one quarter …

The data is from Counterpoint’s Global Smartwatch Tracker.

Apple’s share of the smartwatch market is gradually shrinking as the number of players increases, it says, but the Cupertino company still dominates the market with a 37% market share. This compares well to second-placed Imoo at 10% and Samsung at 9%. Early 2019 estimates suggest Apple will drop one more point this year.

During our last years Q2 2018 preliminary estimates, we overestimated the contribution of Apple Series 1 shipment compared to the Series 3. However, our further supply chain and channel checks revealed the relatively higher contribution of Apple Watch Series 3. As a result, Series 3 becomes the second most popular smartwatch model during 2018 instead of Series 1. ”

Counterpoint says the top five smartwatch models accounted for almost half of all sales.

Estimating sales is difficult given that Apple Watch shipments are a closely-guarded secret, with surveys of sales channels the only clue. Counterpoint and IDC disagree markedly on a number of points – the latter company giving Apple’s share as 27.4% and Samsung in fifth rather than third place – but the two companies do agree on one thing.

  • Apple Watch Series 4
  • Apple Watch Series 3
  • Fitbit Versa
  • Imoo Z3
  • Apple Watch Series 2

The launch of watchOS 6 is likely to help this year, giving owners of older models new reasons to upgrade, including better standalone fitness tracking.

IDC says that ear-worn smart devices will become increasingly important, but told CNET that Apple will remain largely unchallenged in smartwatches.
