Best 377 Watch Battery Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Amazon Basics is the best-performing 377 watch battery brand in July 2026, moving 30,000 units across 1 ASIN for 46.9% of Top 10 volume. DURACELL follows with 11,000 units (17.2%), ahead of Fuspower on 7,000 units (10.9%).
With 8 brands splitting the Top 10 and 75.0% 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 $5.02 to $5.49, which frames the price band a competing listing has to justify.

Trending 377 Watch Battery Products — Growth Leaders & New Top 10 Entrants
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, 2 ASINs forced its way in: B01AVJBH8I booked 2K units at $6.99, with ▲ 100.0% MoM change. On the growth side, B0CRKNY5GM leads positive momentum with ▲ 150.0% MoM growth on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
