The Apple Watch officially launches on Friday, and while it’s not in Apple Store locations just yet, folks who ordered the device early should start receiving them now. If you happen to run into any trouble during your ownership, you should be aware of the damage that’s covered under Apple warranty, and what’s not, details of which were revealed on Friday.

Apple will fix a device under warranty if it finds debris under the display, if the back cover is removed and there’s no damage underneath, and if you happen to find condensation in the heart sensor window. A device might be eligible for out-of-warranty service if the digital crown pops off, if there’s abrasion and scratches on the device from drops, or if there’s damage to the enclosure.

Apple will not fix a unit with missing parts or one that has seen catastrophic damage, like a destroyed device, or if it has counterfeit parts.

As MacRumors notes, Apple will charge $229 for repairs on an out-of-warranty Apple Watch Sport, $329 for the Apple Watch and $2,800 for the Apple Watch Edition. It will also replace the battery for $79 a pop. At those prices, you might want to consider buying Apple Care+ for your new wearable.
