If you don’t get AppleCare+ coverage for your Apple Watch, you could be left with an expensive repair bill if it breaks. But if you’re brave enough, you could attempt to fix the device yourself using one of iFixit’s handy new repair guides.

iFixit are the teardown specialists who pull apart all kinds of gadgets the day they go on sale for our amusement. They also produce some incredibly useful repair guides that’ll help you fix broken gadgets yourself when they breakdown, and they already have four for the Apple Watch.

The guides will walk you through replacing the Watch’s battery, NFC antenna, and display — plus the adhesive that holds the display in place. iFixit also provides many of the parts and tools that you will need, though many of the Watch’s components aren’t yet available.

Before you begin using one of these guides, there are a few things you should know. First, if your Apple Watch breaks down due to a manufacturing defect within the first year — or two if you live in the EU — Apple will repair or replace it for free.

If your device was damaged by you and you don’t want to pay Apple to fix it, just bear in mind that almost all of iFixit’s guides have a “Difficult” rating, and are only intended for those with the right tools and plenty of experience in repairing gadgets with tiny parts.

The last thing you want to do is pull apart your Apple Watch and break other components, making it even more expensive to fix.

Nevertheless, iFixit’s guides will be incredibly useful to many, and there will surely be more to come for the Apple Watch in the coming weeks and months.
