The Miyota caliber 82S7 is from the 8215/821A family but offers a skeletonized dial design. There is also a gilt version available.


Miyota claims that the caliber 82S7 offers accuracy of -20 ~ +40 seconds per day. This is measured within 10-60 minutes from a full wind via the crown. To fully wind the movement, turn the crown 40 times. The winding direction of the rotor is counterclockwise.

82S7 vs 82S0

A more “minimalist” version of the caliber 82S7 is the caliber 82S0. The 82S0 is basically the same movement but has central seconds instead of the small seconds subdial. The 82S0 also does not have the 24 hour subdial.

82S7 vs 82S5

The caliber 82S7 has the following layout:

  • Small seconds at 5:00
  • Open balance (skeletonized) at 7:00
  • 24 hour (can also be day/night) indicator at 9:00

The caliber 82S5 has the same layout, except it does not have the 24 hour indicator at 9:00.

Note: There is also a caliber 82S0 variation which is the same as the 82S5 but with central seconds instead of small seconds.
