Apple Watch debuted six months ago, which was plenty of time to think up all kinds of questions that company didn’t answer the first time around. How long does the battery last? How will Apple Pay work? How much do the things even cost?

Apple put the watch on display again at its recent “Spring Forward” event, and this time gave some concrete details. Here’s everything you need to know about Apple Watch before it goes on sale April 24. Got more questions? Let us know in the comments, and be sure to check back for the full Macworld review at the end of April.

Apple Watch, Apple Watch Sport, and Apple Watch Edition.

So, Apple is finally making a smartwatch, huh? Yes it is—several, actually. The Apple Watch will have three editions, varying in materials and luxury: the Apple Watch, Apple Watch Sport, and Apple Watch Edition.

What are the differences between those three? Apple Watch is made of stainless steel, in a shiny chrome or a space black finish. Its touchscreen is covered by sapphire crystal, which should make it more scratch-resistant than the Gorilla Glass Apple has used on its iPhones. Prices range between $549 and $1,099, depending on whether you buy the 38mm or 42mm case and which band you choose.

Apple Watch Sport has an anodized aluminum case (which is lighter than stainless steel) in silver or space gray, and the face is Ion-X glass, which also designed to be hard and rugged (as well as a little bit lighter) than the sapphire. It’s definitely the lightest of the three Apple Watch editions, making it an ideal exercise companion. It’s also the cheapest option at $349 for the 38mm version and $399 for the 42mm model.

As for the Apple Watch Edition, it ramps up the luxury factor with an 18-karat gold casing in yellow or rose. As you might expect, it’s heavy. Gold, y’know. The Apple Watch Edition also comes in a fancy leather box that doubles as a charging cradle! It also costs about as much as an entry-level car, ranging from $10,000 to $17,000, depending on size and band choice.

Apple’s promotional shots and videos are full of women wearing the watch, which comes in two sizes.

Are there multiple models because one size doesn’t actually fit all? Yes, each edition comes in two sizes, which is something we haven’t seen with any Android Wear watches so far. You’ll be able to get the Apple Watches in heights of 38 and 42 millimeters—about 1.5 and 1.65 inches, respectively, if you’ve had it up to here with the metric system. The Watch’s promotional videos feature plenty of women wearing the watch, which is especially nice to see, since other smartwatch makers appear to be ignoring those of us with slender wrists.

Can you swap out the watch band? Absolutely. Apple announced six bands, and it seems like it’ll be easy to mix and match any band with any watch, swapping them out as your heart desires without the aid of any tools—as long as the band and watch are the same size. (The Leather Loop band, for example, only fits 42mm watches, not the smaller 38mm size.) Apple said it’s come up with its own proprietary system to make switching bands easy—but that also means you probably won’t be able to swap in just any band. And even if Apple’s bands fit your watch, the finish might be different: The solid-gold hardware accents on the rose gray Modern Buckle band won’t match the anodized aluminum finish of the Apple Watch Sport, for example.

Apple Watch Edition

Different body finishes and strap materials let you choose your own look.

For working out, the sweat resistant elastomer Sport Band comes in black, white, pink, blue, and lime green. The Sport Band comes as the default on the Apple Watch Sport, naturally. Weirdly, different colors of the Sport Band have different weights, with black being the lightest.

Owners of the Apple Watch and Watch Edition get three leather straps and two metal straps to choose from. The Leather Loop is designed to be soft and comfortable, with a highly adjustable hidden magnetic closure—you just wrap it around your wrist and the strap sticks to itself to stay closed. That one comes in stone, light brown, and bright blue. Available in pink, brown, and midnight blue, the Leather Modern strap has a two-piece magnetic closure and a subtle texture. And the old-school Classic Buckle strap is a black leather strap that closes with a stainless steel buckle just like the traditional watches you’ve seen your whole life.

Crafted of stainless steel, the Link Bracelet band closes with a butterfly clasp. Apple included a link-release button on several of the links, so you can remove links yourself to customize the fit—instead of having to take it to a jeweler or watch repair shop. That one comes in a regular stainless steel tone or in space black. With myriad tiny, interlocking loops, the Milanese Loop band kind of resembles chain mail, only much more modern. The stainless steel mesh is also magnetic, so you can adjust it to more sizes than you could the Link Bracelet.

When does it ship? Is Apple taking preorders? The Apple Watch ships April 24, but preorders begin April 10. That’s also the same day Apple Stores will have Watches on hand for people to try on, in case you’re not sure which combination of case and band is right for you. If you can’t decide whether you’re steely or sporty, check out our guide to picking the best Apple Watch for you.

Which phones does it work with? Good news: you do need an iPhone to pair with your Apple Watch, but it doesn’t have to be the brand-new iPhone 6 or iPhone 6 Plus. An iPhone 5, 5s, or 5c will work just fine. That’s a big deal since the watch’s $349 starting price might be harder to justify if it also required the purchase of a shiny new phone.

Can left-handed users wear it? Don’t worry, southpaws, Apple hasn’t forsaken you. The Apple Watch works just fine for lefties, because the display rotates. All you have to do is flip the watch over so the Digital Crown is on the left side. Then swap out the band so it’s also in the right position, and then strap the watch to your right wrist. Easy, right?

apple watch activity Apple

The watch can track your daily activities as well as workouts, using its own sensors plus the ones in your phone.

What kinds of sensors does the Apple Watch have? Can it track my heart rate? Apple says that the watch has a couple different sensors, including a gryroscope and an accelerometer (as you’ll find in most smartphones), plus a “custom” sensor that uses visible-light and infrared LEDs along with photodiodes, all on the back of the device, to determine your heart rate. The Apple Watch can also talk to your iPhone’s GPS and Wi-Fi to help with figuring out location and other information.

So it’s a watch and a fitness tracker? The accelerometer lets the watch count your steps, and it extrapolate distance on its own, or rely on the GPS in the paired iPhone to trace your exact route. That step data comes in handy for two of the apps Apple included on the watch: Activity and Workout. Activity shows your progress toward daily goals for moving, exercising, and even standing. Workout is for more detailed tracking of a variety of activities, including distance, pace, time, and calories burned during each session; you can also use that app to set workout goals, and the watch will give you feedback as you reach those goals. Both of the watch’s fitness apps sync data back to the Health and Fitness apps on your iPhone, too. You can’t use third-party fitness apps like Runtastic or Nike+ Running without your iPhone in tow, though.

How do you navigate the Apple Watch? It’s got a touchscreen, right? It does have a touchscreen, but the Apple Watch’s big innovation is the little dial that sticks out the side, also known as the Digital Crown. That’s a high-tech version of the crown you’ll find on standard wristwatches, which you turn to set the time or wind the watch. In the case of the Apple Watch, however, the Digital Crown acts more like the iPod’s clickwheel: You can turn the crown to scroll through a list or zoom in and out of a map. Pressing the Crown returns you to the watch’s home screen, just like pressing the Home button on your iPhone would.

Below the Digital Crown, you’ll find a button, which Apple simply refers to as “the Button.” Press it to access the Friends app, which brings up a Contacts-style collection of the people you like to stay in touch with. Tapping a picture of a friend lets you send them a message, make a phone call, or make contact with the Apple Watch’s Digital Touch features (which we’ll talk about below).

You can touch and tap on the screen too, but if you recall using the sixth-generation iPod nano (the little square one from 2010 that you could buy watch bands for, remember?), the size of your fingertip is bound to obscure part of what you’re trying to tap. That’s why the Digital Crown is there, to let you navigate the Apple Watch while still being able to see the entire screen.

The Digital Crown is sort of like the iPod’s clickwheel: It helps you scroll through options and return to the home screen.

That said, there’s one gesture that works pretty well on even a watch-sized screen—swiping. Swipe up from the clock face to see little bits of information—your calendar, your location, current weather data, and so forth. Apple calls these “glances,” and they strip out the most relevant information from apps and put them into a form you can digest just by looking at your Watch’s screen.

When you do touch the Apple Watch, its screen can actually distinguish between a regular tap, which you’ll use to select things, and a harder touch, which is how you’ll access contextual menus—kind of like right-clicking with your mouse. Apple calls this technology Force Touch, and it’s enabled by tiny electrodes in the display. Check out our hands-on video for a glimpse of how the Digital Crown, Digital Touch, and Glances work in real life.

Can the Apple Watch do anything my iPhone can’t do on its own? Apple showed off a really cool-looking feature called Digital Touch, as we mentioned above, that you can use with other Apple Watch wearers. Digital Touch lets you tap out a pattern on your watch face, which your friend will see and feel on his or her own Apple Watch. You can also draw each other little pictures. And if you hold down two fingers in Digital Touch, you can send your heartbeat, which shows up on your friend’s watch as a glowing, pulsing heart. This might encourage couples to buy his-and-hers watches so they can let each other know anytime how their hearts flutter for each other… or pound like hammers when they get really mad.

Can I use the Apple Watch to pay for things? Yep! The Apple Watch has near-field communication, or NFC, technology, just like the iPhone 6 and 6 Plus. That means you can wave your watch near an NFC-equipped payment terminal to pay, just like you would your new-model iPhone.

Apple Watch brings Apple Pay to iPhone 5, 5c, and 5s owners.

Good news for iPhone 5, 5c, and 5s owners: You don’t need a 6 or 6 Plus to use Apple Pay on the watch. iOS 8.2 just put the Apple Watch companion app on every compatible iPhone, which is where you’ll add your credit or debit card information to store in Passbook. No financial details are stored on the watch itself, but the device does store a token, or a number to act in place of your card number, so you don’t need your iPhone with you to use Apple Pay.

The iPhone 6 models have a dedicated “Secure Element” chip that stores your encrypted information—not your actual credit card numbers, but rather a “device account number” that is used to create a single-use security code to authorize each transaction. The phone provides the watch with information about the items stored in its own Secure Element, and then the watch has the ability to use those items itself in order to pay wirelessly. There’s a nice security touch, too: If you take the Apple Watch off, it’ll lock and require a code before you can purchase anything, so if someone steals your watch they won’t be able to use it as a credit card.

What kind of apps did Apple build for Apple Watch? Will it run third-party apps? Apple went all out for the watch, building in many of the common apps that we use every day: Messages, Mail, Weather, Calendar, Maps, Passbook, Music, Photos, and more. A few notable omissions: While the Apple Watch can act as a viewfinder for your iPhone’s camera, letting you snap pictures and even set the self-timer, it doesn’t have its own built-in camera. Nor does it have Safari, Apple’s Web browser—all the information you get is mediated through those apps.

The MLB.com At Bat app for Apple Watch will display the latest scores right on your wrist.

Still, if what Apple builds into the Watch isn’t enough for you, the company is supporting third-party apps and Glances off the bat. We’ve seen glimpses of how must-have apps like Instagram, Uber, and Twitter will work at launch, and a list of high-profile app partners is here. Indie iOS developers have been able to tap into the WatchKit SDK, which Apple introduced in November, to build their own apps. They shared with us some of their experiences building apps for a device they hadn’t seen in person yet.
