What can replace the Miyota 82S0

7 calibres of the Miyota 82xx group checked against the Miyota 82S0: diameter, height, hand holes, date window, crown and dial feet. A verdict marked “not confirmed” lacks one of those figures for the Miyota 82S0 or the other calibre.

Not published, so not checked in several comparisons:

  • a millimetre diameter for Miyota 82S0
  • hand holes for Miyota 82S0, Miyota 8215, Miyota 82S5, Miyota 82S7, Miyota 8315, Miyota 8N24, Miyota 8205 and Miyota 821A
  • crown position for Miyota 82S0, Miyota 82S5, Miyota 82S7, Miyota 8315, Miyota 8N24 and Miyota 821A
  • dial feet for Miyota 82S0, Miyota 82S5, Miyota 82S7, Miyota 8315, Miyota 8N24, Miyota 8205 and Miyota 821A
