The Apple Watch officially goes on sale April 24, but pre-orders and try-on sessions start Friday, April 10. But buying an Apple Watch will be a little different than getting a new iPhone or iPad. Here’s what you need to know:

When, exactly, can I place an order?

Apple will begin accepting pre-orders on April 10 at 12:01 a.m. PDT. Customers can reserve a watch on Apple’s online store or through its dedicated app. The boldest shoppers can have the watch shipped, sight unseen, directly to their address.

What if I’m not sure about the design and the feel?

Then it’s better to reserve a fitting session. Apple Watches will be available for “preview” fittings on April 10. To manage lines, Apple is launching a new, online reservation system where customers can schedule a five- to 15-minute appointment at the display case. Just pick a watch case and band online, and you’ll be notified when it’s available for pickup at the store. Once there, a representative will make sure it’s the right fit and offer last-minute opportunities to comparison shop.

Do I have to reserve a try-on session?

Apple won’t necessarily turn away walk-in customers, company representatives confirmed in a statement to 9to5Mac, but if past launches are any guide, walk-in customers should be prepared for lengthy waits and inventory shortages. So it’s really better to have a reservation.

Can I browse different models online?

Yes, high-resolution images of every model are conveniently lined up on this gallery on the Apple website. Prices start at $349 for the 38mm Sport version and catapult to $10,000 and up for the gold Apple Watch Edition. As for fitting guidelines, Apple created a handy infographic that shows how cases and bands fit together around the average man and woman’s wrists.

When do I get my Apple Watch?

As always with Apple’s product launches, that depends on where you stand in line, so impatient shoppers should secure their place in the online queue on Friday at midnight Pacific time on the dot. There is one way to bypass the lines, however: Fork over $10,000 or more for the Apple Watch Edition, and you’ll have an hour-long fitting appointment and your own personal helpline, in case further questions come to mind.
