Should I buy a Garmin watch or Apple Watch if I care mostly about sleep?

If you care mostly about sleep, I’d usually lean Garmin for most people.

The biggest reason is practical: Garmin’s much longer battery life makes it easier to wear overnight consistently without having to juggle charging every day. That matters a lot if sleep tracking is the main thing you want.

Simple rule of thumb

• Choose Garmin if your top priority is consistent overnight wear, battery life, and sleep/recovery-style insights.
• Choose Apple Watch if you want the best overall smartwatch experience and sleep is important, but not your only priority.

Why Garmin often wins for sleep-focused buyers

• Multi-day to multi-week battery life on many models makes overnight tracking very practical.
• Garmin’s sleep data is often tied to recovery-style metrics like Body Battery or Training Readiness, which some people find more useful day to day.

Why Apple Watch can still be a great pick

• It’s a very strong smartwatch, especially if you use an iPhone.
• Apple Watch has good sleep tracking, and it can be very comfortable to wear.
• The main tradeoff is battery life: if you miss your charging routine, sleep tracking can be easier to interrupt.

Bottom line: If sleep is your main concern, I’d pick Garmin. If you want the best smartwatch overall and still want solid sleep tracking, pick Apple Watch.
