Slaapscore . My watch says I have had 57 restless moments or was awake 1 hour in total , I only was awake 3 times for toilet? Who is right me or garmin?

Ensure that your watch is snug on your wrist, especially at night. A loose fit can cause inaccurate readings. If that doesn't help, I'd reach out to Product Support through their website at Garmin Support directly to report the issue.
