Before choosing a smartwatch, it’s worth knowing the ecosystem: watchOS only works well with iPhone, while Wear OS and Garmin are compatible with both Android and iOS. Here are six real models currently available on Amazon.es, from most affordable to most premium.

Entry-level: under €300

Enough for notifications, basic activity tracking and several days of battery life.

Mid-range: €300-500

Better screen, more health sensors and better overall performance.

High-end: over €500

Built for serious sport, or for those who want the best in battery life and durability.
