How quickly you will send me the Apple Watch if I order it now?

Apple support won't be able to tell you that either, if you go to the online store and order it you will get an estimated delivery date or call 1-800-MYAPPLE and order it by phone. Keep in mind with the world problems we have right now anything is just a very loose estimate.
