GPS Accuracy: What Actually Matters
Dual-frequency GPS (L1+L5) is now the benchmark for serious athletes. Garmin, Apple, and COROS all offer this on flagship models, delivering sub-meter accuracy even in dense forests and urban canyons. Single-frequency GPS is fine for casual use but loses signal around tall buildings.
Battery Life: The Real Trade-Off
Smartwatch features eat battery. Apple Watch Ultra 2 gets ~60 hours GPS mode; Garmin Fenix 8 Solar stretches to 90+ hours. For ultramarathons or multi-day adventures, battery trumps every other spec.
Training Metrics That Actually Help
HRV tracking, Training Load, and Recovery scores help athletes avoid overtraining. Garmin's Body Battery and Polar's Orthostatic Test are genuinely validated. Most other 'wellness scores' are marketing noise.
Which GPS Watch Should You Buy?
Apple ecosystem users: Watch Ultra 2 is unmatched for integration. For sport-specific depth — triathlon support, trail navigation, cycling power — Garmin Fenix 8 is the gold standard. Budget-conscious runners should look at COROS PACE 3.
