Quick answer: Evaluate whether wrist sleep tracking is strong at trends and weak at absolutes, so choose for the routine you will actually keep rather than the longest feature list. Confirm an overnight wear habit fits your charging schedule, because a watch sitting on a cable at bedtime records nothing. Compare the options in the table on comfort and morning reporting first — sensors matter less than whether you keep wearing it.

How many nights before the data means anything?
A week is the floor; several weeks is better.
Is the nightly score worth acting on?
Treat it as a conversation starter, not a verdict.
Ask about band fit before committing to overnight wear
Check sizing against your measured wrist, and look for a softer strap option if the included this choice irritates you after a few hours.
What a watch can and cannot say about apnea
Wrist sensing can flag patterns that deserve attention; it cannot diagnose.
