Miyota 9039-VS-9015

The Miyota 9039 is an automatic movement manufactured in Japan. It operates at 28,800 vph and measures 3.9mm in height. The 9039 is essentially a no-date version of the 9015, featuring lower hand stack height (1.75mm versus 2.1mm), which allows it to fit in cases as thin as 8.25mm compared to the 9015's 8.6mm minimum. Both movements share identical dial feet locations, making interchangeability possible in some cases, though stem specifications require verification. The 9039 has a single crown position for time setting, whereas the 9015 includes an additional position for date adjustment.
