Case 13 — Model comparison: dive bezel action and alignment, how to compare fairly

Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.
