Last week a report suggested that Apple will require customers to have reservations in order to come into Apple Store locations to purchase the Apple Watch. Freshly leaked documentation published by MacRumors supports that sales method, and suggests there will be additional limitations.

MacRumors said recently that Apple will require all customers looking to buy an Apple Watch in person to create a reservation with sales staff. That means you can’t just walk in off of the street to buy one, at least not initially. This reservation system is only to try on the Apple Watch, too, which means that Apple isn’t going to promise availability of the various models.

This is certainly a different approach to Apple’s standard product launches, which usually encourages customers to line up and buy new products on launch day. It suggests there may be a shortage of hardware at launch, but you should be able to guarantee your new Apple Watch by ordering a unit online, at least.
