You don't have to book or have an appointment before you can have a hands-on with the Apple Watch as there will be enough for everyone. Also, Apple retail staff will be on ground to walk you through the wrist-on experience. If you like the feel of a particular Apple Watch model--the Apple Watch Sport, Stainless steel Apple Watch or the Gold Apple Watch-- you can schedule an appointment to pick it up when the Apple Watch smartwatch goes on sale on April 24th.
Now to better guide interested customers through the hands-on experience, the sources say Apple will separate its employees into four zones: One zone will to you in trying on the cheaper models of the Apple Watch, the aluminium Watch Edition and Sport Stainless Steel Apple Watch(which include two lines: one for people who know exactly which Apple Watch they want to purchase, and another for those who still are undecided about the right watch casing and band choice). The second zone will handle sales. While third and fourth zones will be customer service representative and experts who will assist buyers of the Apple Watch gold edition. These are Apple employees with years of experience working for the company.
