Miyota

Miyota's no-date variant of the 9015 platform, eliminating the date complication for a cleaner dial design. At 4.0mm thick it is notably slimmer than the 9015, making it attractive for watches where case thickness matters. The absence of a date mechanism also means one fewer point of mechanical complexity, and many watchmakers consider it the most refined movement in Miyota's lineup.
