Smartwatch Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Apple is the best-performing smartwatch brand in July 2026, moving 28,000 units across 3 ASINs for 38.4% of Top 10 volume. Garmin follows with 21,000 units (28.8%), ahead of Fitbit on 15,000 units (20.5%).

With 5 brands splitting the Top 10 and 87.7% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $125.06 to $289.00, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0DYJKTHYF booked 4K units at $79.00, with ▲ 100.0% MoM change. On the growth side, B092RCLKHN leads positive momentum with ▲ 40.0% MoM growth on 7K units, with B0F9FJ2DB1 close behind at ▲ 25.0% MoM on 500 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
