    Miyota 9015 movement is a remarkable upgrade from its predecessor Miyota 8215. The reason I say 9015 is an upgraded version of 8215 is because 9015 has made a lot of improvements. For example, 9015 accuracy is ー10~+30 sec/day, while 8215 movement accuracy is -20~+40 sec/day.

    Miyota 9015 is an automatic movement, meaning it winds itself using the natural motion of the wearer’s wrist. Miyota 9015 operates at a frequency of 28,800 vibrations per hour (vph), ensuring precise timekeeping. Featuring 24 jewels, this movement offers a power reserve of approximately 42 hours, making it ideal for daily wear with no frequent winding.

   We know Myota 9015 for its slim profile, measuring only 3.90 mm in thickness. This makes it suitable for watches with thinner cases, providing a sleek and elegant aesthetic.

Miyota 9015 vs nh35

  Compare Miyota 9015 vs NH35 calibers, both of them are popular non-Swiss made movements. Both have reliable performance, but there are some significant differences.

Vibration Frequency

     We know the rate at which the balance wheel oscillates and regulates the beating of the watch as the frequency. Seiko NH35A caliber beats at a frequency of 21,600 beats per hour, while the Miyota 9015 automatic movement beats at 28,800 beats per hour. A movement with a higher frequency will provide a more accurate progression because the movement with a higher frequency will recover faster when the watch is shocked. Also, with chronograph automatic watches, the higher frequency movement allows for more accurate time measurement.


   NH35 movement accuracy is -20~+40 sec/day, Miyota 9015 accuracy is -10~+30 sec/day. so 9015 movement is more accurate NH35.

Rotor winding direction

   We can wind the rotor of the NH35 movement in both directions. The Miyota’s rotor can only be wound clockwise.


  Comparing with NH35, the price of Miyota 9015 movement is much higher. Miyota 9015 is about $70~$85, while the price of NH35 movement is about 35 dollars.

   So in all Miyota 9015 movement has a smoother and more accurate second hand. As for some subtle differences, please refer to the chart below.

   ETA 2824 is a widely recognized Swiss movement known for its accuracy and craftsmanship. Comparing vs Miyota 9015, both have a frequency of 28,800vph and are very close in terms of accuracy and functionality, but there are still a few key differences worth considering.

Rotor winding direction

  The rotor of the ETA is bi-directional, like that of the NH35, while the rotor of the 9015 caliber can only be wound in a clockwise direction.

Running time
