Apple Watch 2 specs
Apple Watch boasted a significant amount of new technology and design features, such as the Digital Crown, Force Touch sensor, Taptic Engine and customisable watch faces.
Features that are likely to remain largely the same on the Apple Watch 2 include the Digital Crown and Taptic Engine.
We would also expect some incremental improvements, such as 3D touch (as seen on the iPhone 6s) replacing Force Touch and additional watch faces.
Several of the new features of the original Apple Watch were unforeseen, so it is quite possible the Apple Watch 2 will include technology that no one has yet speculated on.
The original Apple Watch featured the S1 "system-on-a-chip", which was built specifically for the smartwatch, as well as an optical heart rate sensor on the rear of the case and standard fitness sensors including an altimeter, gyroscope, pedometer and accelerometer. The Apple Watch 2 will likely feature a new SoC (we would imagine this would be called the S2, as per the naming convention for Apple's iPhone SoCs, which follow a standard numerical pattern).
Existing sensors are likely to remain, but others could be introduced as well.
