Does my Watch backup live locally or in iCloud?

When you sync data between your Watch and iPhone for the first time, the information is stored locally on your iPhone. When you back up your iPhone, some of the information will sync to iCloud (for example, if you have your Health data in iCloud); the remainder will save to either iCloud or iTunes, depending on the backup method you use.
