What to verify before choosing
- Wrist heart rate lags on intervals — pair a chest strap.
- Check which metrics sit behind a subscription.
- Battery claims assume GPS off; read the sport-mode number.
If a specification, certification or compatibility detail is absent, mark it as unknown and ask the seller or manufacturer. Do not substitute a star rating, an editorial score or a different model's specification.
