My watch's lume is bright for a few minutes and then barely visible. Is that normal? People post lume shots of different watches, but they all seem to use different charging and exposure, so I can't tell what's actually better.

A bright initial glow followed by a steep drop is normal for photoluminescent pigments. Afterglow fades fastest in the first minutes and then settles to a dim, long-lasting level that dark-adapted eyes can still read. The real question is whether it's readable after an hour in darkness, not how it looks right after charging.

Clarifying question: how are you charging it? A few seconds under a warm indoor bulb gives a much weaker charge than daylight or a UV source. Many 'weak lume' reports turn out to be undercharging. Try a consistent charge, such as 30 seconds under a phone flashlight at a fixed distance, before judging.
