Businessweek’s Profile on Tim Cook’s Apple

There are a few interesting tidbits about Tim Cook and the Apple Watch in Businessweek’s profile from last week, including this one:

The watch team included hundreds of engineers, designers, and marketing people and was the kind of cross-company interdisciplinary team now common under Cook. Apple, which has more than 1,000 chip designers, built the new S1 processor that powers the watch. Metallurgists responsible for the casing for Macs and iPhones devised a stronger gold alloy for the premium model of the watch, and Apple’s algorithm scientists studied how to improve the accuracy of the watch’s heart rate sensor.
