Apple is now preparing for the rollout of the in-store pickup option on new Apple Watch orders, which will allow users to select a retail location to pick up their wearable devices after order. This is the first time Apple has made any indication of watch stock appearing at its stores since Angela Ahrendts revealed that the company was unsure of when that might happen.

The radio button to select the option is currently disabled, but is expected to be turned on once local stores start to see shipments arrive.

I tried adding a number of different watches (one at a time) to my cart and could not get this option to appear, so this might be a regional rollout.

I wonder if they will give buyers who have been waiting a month or more for their Apple Watch to ship the first crack at in store pickup.
