Apple officially debuted its latest smart watch, the Watch Series 4, this week. “The company’s next-generation smartwatch features the first major redesign since 2015’s original (“Series 0”) model, including larger bodies, over 30 percent bigger screens, and new internals,” Venture Beat writes. “Despite a 35 percent larger screen on the smaller version and 32 percent larger screen on the larger model, it’s thinner than the Series 3, with less total physical volume.”
