Going by Apple's track record with the iPhone, chances are, the Apple Watch 2 may not be radically different from the Apple Watch. However, Apple is firm on the fact that the Apple Watch 2 needs to function independently and this could add credence to a new rumour that the Apple Watch 2 might be getting an inbuilt GPS module.
9to5Mac reported that the Apple Watch 2 is said to have GPS support, which will be used as part of the fitness tracking features included in watchOS 3. With watchOS 3 the Apple Watch and the Apple Watch 2 get a host of fitness functions that include native apps, enhanced tracking and the ability to share fitness stats.
The GPS function added to the Apple Watch 2 could mean that users wouldn't have to keep their iPhones with them while going for a run and could simply let their Apple Watch 2 count their steps and map their performance.
Ever since Apple demanded that all watchOS apps should become independent, things have been pointing towards the Apple Watch 2 being an un-tethered device. It's been rumoured to feature cellular data, the ability to make facetime calls with a built-in front camera. GPS only frees the Apple Watch user from having to lug their iPhone with them everywhere they go.
Added GPS could also help parents breathe easy. Anxious parents of young(ish) children could use the GPS built into the Apple Watch 2 to find out where their kids are. Third-party developers and even Apple could develop apps that could allow wearers of the Apple Watch 2 to notify preset contacts in the case of an emergency and finally, GPS tracking could reunite Apple Watch 2 owners with their lost or misplaced devices.
The Apple Watch 2 is expected to be released sometime in September this year alongside the iPhone 7 and the iPhone 7 Plus. There's still no official word on a date though.
