Worldwide smartwatch sales dropped 51.6 percent year-on-year in the third quarter of 2016 to 2.7 million units, hit by limited availability of Apple Inc's Series 2 and a general falloff in sales, according to a report by research firm International Data Corporation.

Apple maintained its lead position in the worldwide smartwatch market and shipped 1.1 million devices. But its market share tumbled to 41.3 percent from 70.2 percent, as sales fell nearly 72 percent year-on-year.

Garmin posted the sharpest rise among the smartwatch manufacturers, with sales rocketing 324 percent to 600,000 units.
