The new Apple Watch will be more attractive to endurance athletes and outdoor enthusiasts with the timepiece’s improved geo-location capabilities and waterproofing features.

Runners and cyclists, among others, will appreciate the rumoured “Apple Watch 2” equipped with global positioning system (GPS) radio and barometer. Apple Insider reported that these features will allow the wearable device to track its user’s movements accurately even without a nearby iPhone.

But due to the improvements and additional sensors, the "Apple Watch 2" will require a higher capacity battery, prohibiting the device’s slimming unlike other Apple devices. The original Apple Watch comes in two sizes but both are 10.5 millimetres in thickness.

Aside from "Apple Watch 2," consumers have the option to purchase an upgraded version of the original Apple Watch, which according to Apple Insider, will sport the same aesthetics as that of the original but with improved processors and waterproofing.

In its report, Apple Insider quoted KGI analyst Ming-Chi Kuo, who told investors that the new Apple Watches will be launched in the second half of 2016. It is not exactly certain if the Apple Watch units will be unveiled alongside the new iPhone models this September.

Nevertheless, Kuo said he doesn’t expect radical changes in the Apple Watch design until 2018 when Apple could secure FDA approvals of its improved health applications.
