Over the past few years, the Tsuyosa line has expanded to offer a wide range of versions, including a 37mm sizing, a small seconds version (also 40mm and with a 60-hour power reserve), and the standard automatic Tsuyosa, which is 40mm wide but utilizes a cal. 8210 with 42 hours of power reserve. With this new 60 series, you get an expanded power reserve, but without the small seconds display, offering a cleaner and more classically derived look that is closer to the original inspiration from Citizen’s NH-299 series.
