The differences between these two iterations have been covered extensively, but a question to those who might have both models, or know the specifications:

Look at the two crowns. There are obvious differences - the newer one gets thinner as it nears the case. But here’s what I’m wondering: did they keep the outer edge diameter of the crown the same as the older model, or is it slightly increased?
