Along with announcing Apple Watch Series 2, Apple is also partnering with Nike. The relationship between these two companies has been around for a while, and this is the first time they are partnering for the Watch. The Apple Watch Nike + is meant to be a running partner.
In comparison to regular Watch Series 2 models, it features a lightweight aluminum case, a particular shortcut to start a run and a unique perforated band. It will be available in four different colors matched with a band.
