Juniper Research claims the manufacturer sold 8.89 million units last year, while total smartwatch sales hit 17.1 million
Apple claimed 52 per cent of global smartwatch shipments in 2015, despite only launching last April.
This is according to new data from Juniper Research, which said there were 17.1 smartwatches shipped last year, meaning Apple accounted for 8.89 million units.
It states the first wearable from the Californian tech giant far eclipsed that of rival vendors, with Android Wear shipments comprising less than 10 per cent of sales.
Juniper said the volumes are reflected by the number of apps available for each platform; in September, Apple reported 10,000 apps available while Android Wear reported 4,000 apps in May.
It said that according to its research, the Samsung Gear S2 did not achieve strong sales volumes since launch in November, despite being well received. Juniper did not reveal sales figures.
Juniper added that with no new releases until the Gear S2, much of the year comprised of below-the-line sales of existing Gear models, without promotion to drive sales.
However, because of its late 2015 release, it expects the majority of sales to be made this year but the lack of apps and devices for Tizen means there will be less users drawn to the platform.
