Keep it as an Emergency Spare

This is probably the least exciting option on the list, but it’s also one of the most practical. Instead of immediately selling or recycling your old Apple Watch, keep it ready as an emergency spare. If your main Apple Watch breaks, gets lost, or needs service, having a backup means you don’t lose all your favorite Apple Watch features at once.

That matters more than you might think. Once you get used to alarms, workouts, notifications, and other useful features right on your wrist, suddenly losing the watch entirely can feel more disruptive than expected. A backup solves that problem quietly.
