Case 22 — Lume questions: why does my lume fade so quickly, and how should I compare it?
A practical test without a camera: charge both watches the same way, sit in a dark room, and check readability at 5 minutes, 30 minutes and 2 hours. Write down which you can still read the time on. It's subjective but repeatable, and more useful than a single photo.
