Amazfit T-Rex 3
Score: 78/100
Apple Watch SE 3 40mm Starlight
Score: 81/100Rankings

The Apple Watch SE 3 40 mm GPS model provides snappy performance, an always-on display, and core health tracking in a lightweight recycled aluminum case. It lacks cellular and some advanced sensors, and battery life remains limited to a single day. Great for iPhone users wanting a budget-friendly, feature-rich smartwatch.

The Amazfit T-Rex 3 is a rugged outdoor smartwatch featuring a 27-day battery, dual-band GPS with offline maps, and a 2000-nit AMOLED screen. Its bulkier case and limited app ecosystem are notable trade-offs. Best suited for hikers, freedivers, and adventure seekers who value durability and navigation over a slim profile.
