- 2-year US warranty and improved battery make it ready for all-day, all-night wear
Cushion design plus Galaxy AI make this the Wear OS watch for people who want lighter hardware, smarter training, and clearer recovery insights.
Why we like it
- Sleep smarter – Advanced Sleep Coaching plus Bedtime Guidance keep your night routine consistent, and the new Energy Score uses Galaxy AI to turn sleep + heart + activity into one actionable number.
- Running coach on-wrist – Select a program (5K to marathon) and get live guidance on pace, cadence, and form. Vascular Load monitoring tells you when to dial intensity back.
- Sleeker hardware – The cushion chassis is thinner and hugs your wrist so sensors stay snug during workouts. It’s lighter than Watch6 Classic yet still packs IP68 + 5ATM durability.
- Power + assistant – A larger battery keeps heart rate, notifications, and workouts going through busy days, while the refreshed UI and Galaxy AI assistant surface weather, scores, and news at a glance.
Setup tips
- Update firmware right after pairing—battery tuning and Galaxy AI enhancements arrive in the first patch.
- In Samsung Health, enable Sleep Coaching reminders and Bedtime Guidance to lock in consistent rest.
- Add the Running Coach tile plus heart-rate zone tile so you can start guided runs with two taps.
- Customize gestures: double-pinch for AI assistant, double-fist-clench for flashlight. Helps keep the minimalist hardware button-free.
Accessory pairings
- Slim TPU bumper for cushion-style cases—you protect glass without ruining the silhouette.
- Nylon stretch band for sleep tracking nights; swap to a fluoroelastomer strap for sweaty runs.
- USB-C fast puck with travel brick (30–45W). Fifteen minutes nets hours of wear thanks to the improved battery chemistry.
