Case 21 — Model comparison: dive bezel action and alignment, how to compare fairly

Separate three properties: click count (60 or 120 positions), feel (how firm each click is, and whether there's back-play), and alignment (whether the pip lines up with the 12 o'clock marker at rest). Crisp vs mushy is mostly about feel and back-play. Alignment can be measured, so treat it separately.
