Orient Kamasu Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

CITIZEN is the best-performing orient kamasu brand in July 2026, moving 1,500 units across 7 ASINs for 55.6% of Top 10 volume. Invicta follows with 500 units (18.5%), ahead of Casio on 400 units (14.8%).

With 4 brands splitting the Top 10 and 88.9% 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 $89.95 to $246.60, 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, 2 ASINs forced its way in: B016R90VBK booked 200 units at $238.00. On the growth side, B0B6KWJ4KJ leads positive momentum with ▲ 50.0% MoM growth on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
