Apple Watch Series 12 vs Polar Vantage V3
Our pick: Apple Watch Series 12 takes it — 84 vs 78.
Both are strong — the call comes down to what you prioritise:
- Apple Watch Series 12 — You're on a Series 9 or older and want the most accurate wrist heart rate Apple has made, plus a readiness score you can use to steer clients' training, with no subscription.
- Polar Vantage V3 — Serious triathletes and multisport/endurance athletes who want deep training and recovery data plus long battery life.
Apple Watch Series 12
The new Health Sensing System is the real upgrade: heart rate every five seconds, far more frequent HRV and a daily Readiness score, with testers finding it close to a chest strap. Battery is still rated at 24 hours and the design is unchanged, so Series 11 owners can skip it.
Polar Vantage V3
A hardware powerhouse for serious endurance and multisport athletes: class-leading battery, dual-frequency GPS and a deep sensor suite (ECG, SpO2, skin temperature). The training and recovery analytics are outstanding, but the smartwatch side stays barebones and the price only makes sense on discount.
