Apple's suppliers have already begun producing the iWatch in small quantities, according to supply chain sources cited by China Times via G for Games, ahead of a prospective launch during the second half of 2014. Echoing an earlier report from notable analyst Ming-Chi Kuo, the site's sources also suggest the iWatch will take advantage of a system-in-package (SiP) design that allows a multitude of chips to be placed on a single module. This could allow Apple to the fit multiple sensors rumored for the smart watch into a tiny area while keeping the device small enough to be worn comfortably on the wrist.
