The highly-anticipated Apple Watch 2 is being geared up for a summer release, reports suggest.

Wall Street analyst Brian White has been teasing that Apple could unveil its next-generation wearable in time for the Worldwide Developers Conference in June.

New features for the Apple Watch 2 have been tipped to be a case that's 20%-40% skinnier and a greater versatility when not tethered to an iPhone, Digital Spy said citing TechRadar.

Apple traditionally unveils major new products at autumn and spring media events – but this move would certainly vary from that schedule, Digital Spy said.

Apple Watch shipped an impressive 4 million units when it was released one year ago – and recently received a whole new range of add-ons.
