The T-Rex 3 is Amazfit doing what Amazfit does: most of an expensive watch for a third of the money. A 2,000-nit AMOLED in a 48.5mm shell rated to 10ATM and certified for 45m diving, 27 days of typical use, 42 hours of dual-band GPS, and offline maps with turn-by-turn included rather than sold as an upgrade. Zepp OS 5 added BioCharge energy scoring, so it finally has the daily readiness metric the older T-Rex Ultra never got. There is a microphone for the voice assistant but no speaker, so no calls, and contactless pay is not enabled on US units.
Strengths
- 27-day typical battery and 42 hours of dual-band GPS
- Free offline maps with turn-by-turn navigation
- 10ATM plus a 45m dive certification at $279
Tradeoffs
- No speaker, so no Bluetooth calling
- No contactless payment on US units
- 68g is heavy on a smaller wrist
