The digital crown represents a crowning achievement in Apple's engineering portfolio.

This single knob fluidly and effortlessly combines the styling of old with the functionality of new, to bring Apple's renowned intuitiveness to your fingertips.

Simply pull out on the knob and rotate to adjust the time. Push it in when you're done, and Apple Watch does the rest. Interfacing with technology has never been easier.

Flipping the Apple Watch over, we find its fashionable and functional brushed stainless steel rear cover, featuring "Contemporary Design."

Apple made an excellent design choice with stainless steel—it is highly corrosion resistant, and a fairly safe alloy for people with nickel allergies, as it keeps the alloyed nickel tightly bound within its structure.
