Sharing an Apple Watch

As julieda stated, while you can pair more than one watch to a single phone, you cannot pair one watch to multiple phones without un-pairing to one phone and then pairing to the other. There is no toggle to switch, since the watch cannot hold more than one profile.

In a way you can read and understand, no, it’s not possible. The Apple Watch and iPhone are single user devices. It would be extreamly unwise to share a Watch with your ID with another person.

Apple lends users the ability to pair more than one Apple Watch to a single iPhone. It has not, however, allowed the ability to connect more than one Apple Watch at the same time. While you can have multiple Apple Watches paired, you can only use one at a time.
