Watch distance
How far can I travel without my watch being by my phone
Question marked as
If this is a GPS Only Apple Watch, then Bluetooth range is 10 to on a good day 20 meters (30 to maybe 60 feet).
If both your Apple Watch and iPhone are on the same home WiFi network, then they can continue to communicate until one of them moves out of range.
Note, if you are just barely in Bluetooth range, it will choose Bluetooth over WiFi, and may experience performance issues for higher bandwidth demands. For example an iMessage my go through easily, but a voice phone call my have difficulties. Move a little more out of Bluetooth range and a phone call may drop.
A cellular Apple Watch can be on the other side of the Earth, as long as both the Apple Watch and the iPhone are powered on, and have access to the internet ( iPhone is also logged into iMessage, and both devices are logged into the same Apple ID)
