Why buy each?

COROS Apex

65h GPS, 24-day battery (46mm)

The 46mm Apex 4 delivers 65 hours of GPS tracking and 24 days typical use — enough for multi-day mountain events without charging. The 42mm offers 41h GPS and 15 days.

Full offline maps and depth gauge

Global topographic maps with instant rendering, turn-by-turn navigation, POIs, and an underwater depth gauge — the Apex 4 is the first COROS mid-tier with a depth sensor.

Speaker, microphone, and voice notes

Audio alerts, hands-free calling, and voice pin recording — a first for the Apex line, adding practical trail and daily-wear convenience to this mountain sports watch.

Amazfit Band 7

18-day battery at under $50

18 days of typical use with health monitoring — nearly 3 weeks without charging, far beyond any smartwatch competitor.

Alexa built-in

Ask Alexa for weather, timers, reminders, and smart home controls directly from your wrist — unusual for a sub-$50 fitness band.
