The latest data from market research firm IDC estimates Apple Watch sales totaled 3.6 million worldwide in the second quarter of 2015, making it the second most popular wearable device during the three-month period ending June 30. Apple was within striking distance of market leader Fitbit, which sold an estimated 4.4 million fitness trackers in the second quarter.

IDC estimates that Chinese electronics maker Xiaomi trailed in third place with 3.1 million wearables shipped in the quarter, representing 17.1% market share. Garmin and Samsung rounded off the top five with 700,000 (3.9%) and 600,000 (3.3%) wearables shipped respectively, while all other vendors accounted for a combined 5.7 million shipments and 31.5% market share.

Last month, Strategy Analytics estimated 4 million Apple Watch sales in the second quarter, so IDC's estimate is within close range. Apple has not disclosed Apple Watch sales numbers since it launched in April, instead grouping the wrist-worn device with iPod, Apple TV and Beats Electronics accessories under an "Other Products" category in quarterly earnings reports.
Apple CEO Tim Cook vaguely mentioned that Apple Watch sales have "exceeded expectations" during an earnings call last month.
