Visual differences between H-factory lowbeat and 111J highbeat?

[RobbDizzle]

So we all know that these new H-factory PAMs are pretty damn good out of the box. One of the only tells is the movement, which is a lowbeat movement at 18,000 bph vs. the more accurate 21,600bph highbeat movement. Honestly when I put it on, the slower ticking really got to me...maybe I'm just used to the sound that a highbeat PAM has. consequently, I'm thinking about the swap. My question is, what are the visual differences between the two? I was looking at a 111J picture and holding my 177L up to the screen, and I couldn't for the life of me pick anything out. I'm too much of a PAM noob still...enlighten me!

So it has to do with the difference in beat specifically, because the balance wheel moves slower?
