legend how does the open case back movement look to you ? I know the 15400 is a dead give away because the balance wheel doesn’t have those little ball looking things on it , but what about the looks of this movement? Still a dead give away?
It’s a dead giveaway of course, not just the balance wheel but the entire caliber. The looks of the jewel, engravings and finish are nothing like the gen. For the balance wheel it’s not about the way it looks but the position of it VS the gen.
Were you referring to the rotor assembly instead when you mentioned bearings? Be it 15400 or 15500, they use the same base movement and neither of them resembles the gen in the slightest.
But I agree with aristole, the movement decorations are perfunctory at best and insignificant when watch is worn on the wrist. The decorations are pointless because nobody should want to admire a miyota 9015 movement, decorated with faux plates and faux jewels and poor finishing and engravings. The miyota 9015 is a movement befitting a $400 watch and reliable and a good alternative to the gen caliber: both make the watch tick on the wrist and aren’t seen when watch is worn.
So if you’re asking me, yes the caliber is a tell. An instant tell when viewed by someone who knows what to look for. But it is a tell which does not matter when you’re wearing the watch.
