I am wondering why the Miyota 8315 it's no so popular could it be because the price ? Actually it doubles in price the 8215
It's exactly the same measures of the 8215 with the exception that 8315 is 60 hrs reserve and
They said "Decorated" but actually what I can see is the rotor lightly better looking and some blue screws
But in general I think is better movement.
I would love to hear any opinions
