AI summary of 5 reviews · as of Aug 2026
Reviewers agree the Apex 4 is a durable, long-battery-life outdoor watch with strong GPS and heart rate accuracy, but its memory-in-pixel screen and plastic case will disappoint anyone expecting a bright AMOLED look or premium metal build.
What they praise
- Long GPS and daily battery life across both case sizes
- Accurate GPS tracking and reliable heart rate readings versus chest straps and other watches
- Improved button layout with new action button reduces accidental presses
- Detailed offline mapping with street and trail names, plus voice pin and voice memo tools
- Sapphire display and titanium bezel add scratch resistance and durability
What they knock
- Memory-in-pixel display is harder to read in shade or off-angle compared to AMOLED screens
- Case is now fully plastic apart from the bezel, a step down in materials from the previous Pro model's metal back
- No smartphone music playback controls despite onboard music storage
- Occasional heart rate spikes at the start of runs and confusion after stop-restart
