Lenovo's next version will have a "modified design" and would be "more beautiful and more like a clock". Expect a launch this September.
The ZenWatch 2 comes in two sizes. The displays for both are the same 2.5D curved AMOLED, and the only real design change is the addition of a standby button on the side in the form of a watch dial.
The next Samsung Gear's rotating bezel adds physical controls to the touchscreen setup. It can be used for a number of navigation actions including scrolling, zooming and adjusting levels.
