How to transfer data, series 6, while watch is being exchanged

Hi cinda100,

Thank you for participating in the Apple Support Communities. Your Apple Watch data is backed up to the iPhone you're using it with. You can choose to restore the backup when you set up the new Apple Watch. This article explains more about this: Back up your Apple Watch - Apple Support.

"Learn how your Apple Watch data is backed up and what the backup includes.

How Apple Watch backs up your data

Your Apple Watch data is backed up to the iPhone that it's paired with.* This happens automatically as long as your iPhone and Apple Watch are near each other, so you don't need to do anything to keep your watch backed up.

When you unpair your Apple Watch from your iPhone, the watch is backed up completely to your iPhone to make sure that the latest data is saved. You can use the backed-up Apple Watch data on your iPhone if you ever need to restore your Apple Watch, or when you set up a new Apple Watch.

When you back up your iPhone to iCloud or your computer, your iPhone backup includes your Apple Watch data. This means that when you set up a new iPhone and restore it from backup, your latest Apple Watch data is also restored.

* If you've set up an Apple Watch for a family member who doesn't have an iPhone, the watch's data is backed up to iCloud directly. Learn more about backups for an Apple Watch that you set up for a family member.

Here's what your Apple Watch backup includes

• App-specific data (for built-in apps) and settings (for built-in and third-party apps). For example, Maps, distance, units, and your settings for Mail, Calendar, Stocks, and Weather. 
• App layout on the Home screen
• Clock face settings, including your current watch face, customizations, and order 
• Dock settings, including the order, whether you sort by Favorites or Recents, and available apps 
• General system settings, such as brightness, sound, and haptic settings
• Health and Fitness data, such as history, awards, Workout and Activity calibration data from your Apple Watch, and user-entered data (To back up Health and Fitness data, you need to use iCloud or an encrypted backup on your computer.)
• Notification settings
• Playlists, albums, and mixes that are synced to your Apple Watch, and your Music settings
• The Siri Voice Feedback setting that controls when Siri speaks 
• Synced photo album (To see which album syncs, open the Apple Watch app, tap the My Watch tab, then tap Photos > Sync Album.) 
• Time Zone"

We hope this helps.

Take care.
