Well-connected KGI analyst Ming-Chi Kuo in a note to investors on Sunday, obtained by AppleInsider, detailed Apple’s wearable timeline for the coming six months.

Kuo believes Apple is planning to launch two new Apple Watch versions in the second half of 2016, both of which offer moderate improvements over their predecessor. The first unit will be an iterative upgrade on the original Apple Watch and is expected to sport the same aesthetics, but with improved intervals like a TSMC processor built on the 16nm process. Waterproofing should also be slightly improved.

A second version, dubbed “Apple Watch 2,” is also expected to share the same general design as current models, but will include a GPS radio and barometer for improved geolocation capabilities. A higher capacity battery will be included to power the advanced components, but its size will prohibit Apple’s usual generational device slimming.
