Miyota
Miyota's premium automatic caliber positioned as a Japanese alternative to the ETA 2824-2 and Sellita SW200-1. The 9015 adds hacking, hand-winding, and a smoother 28,800 vph beat rate over the budget 8215. Its thinner profile and higher jewel count make it a favorite among microbrands seeking a reliable mid-range movement that punches above its price point.
