what is the difference between the nike apple watch and the series 2 apple watch?

Hi

Apple no longer sells new Apple Watch Series 2 models (although they may remain available from some Apple Authorised Resellers).

Apple Watch Nike+ models feature include a Nike Band, exclusive Nike watch faces (along with the standard Apple Watch watch faces) and closer integration with the Nike+ Run Club app. The Nike watch faces include a permanent complication / shortcut for launching the app.

All of the Nike+ models feature an aluminium case and Ion-X glass. Some other Series 2 and Series 3 models have a stainless steel case (which is heavier) and sapphire crystal (which is more scratch resistant).
