The Apple Watch NikeLab will be available from April 27 from Nike.com, NikeLab doors, and the Apple Watch Store at Isetan Shinjuku.
In a blog post announcing the launch, Nike says "The limited edition, neutral-toned Apple Watch NikeLab maintains the beloved features of its predecessor: deep integration with the Nike+ Run Club app, exclusive Siri commands, GPS, a two-times-brighter display and water resistance to 50 meters, all made possible by a powerful dual-core processor and watchOS 3."
"Apple Watch NikeLab is the ultimate style companion for those with a passion for running, whether emerging runners or marathon veterans," the blog post adds.
