There can be numerous instances where you unpair an Apple Watch from an iPhone but the following are the most common scenarios: 

Unpairing the Apple Watch Means

Unpairing an Apple Watch means restoring the Watch to its factory settings and wiping all its data but a backup of the data will be created if the process is done on an iPhone, otherwise, the data may be lost. Moreover, whenever you back up the iPhone to iTunes, iCloud; that backup may also have data from the Apple Watch. This data can be later on used to re-setup the Apple Watch after pairing it to an iPhone (with the Apple credentials used to back up the Watch). So, in simple words, unpairing an Apple Watch from an iPhone will erase all the Watch data but if the unpairing is done through an iPhone, then the data will be backed up to the iPhone.
