Prerequisite only guide for opening up the Apple Watch Series 10.

Before starting this repair, remove your watch from the charger and let its battery drain completely—the watch should shut down from low battery. A charged lithium‑ion battery may catch fire if damaged.
Letting the battery drain completely also prevents accidentally turning your watch back on when gripping it during repair.

Throughout the rest of your repair:
Attach and remove the watch bands as needed to get a better grip or stabilize your watch.
To remove a band, firmly press in the small, oval button on the underside of the watch and slide the band out of its groove.
Consider placing your watch on something soft like a clean cloth to help stabilize it and prevent damage.

If inserted too far, an opening pick can damage your watch. Follow this step to mark your pick and prevent damage.
Measure 3 mm from the tip and mark the opening pick with a permanent marker.
Alternatively, tape a coin to a pick 3 mm from the tip.

Strong adhesive secures the perimeter of the screen to the frame. Heating the screen softens the adhesive, making it easier to separate.
Heat an iOpener and lay it on the screen for two minutes to soften its adhesive.
Alternatively, you can use a hair dryer or heat gun—but be careful as extreme heat can damage the screen and/or battery.

iFlex Opening Tool

$11.99

The gap between the screen and frame is extremely small. You'll need a thin tool such as an iFlex to create an initial gap.
Don't grip the iFlex or similar metal tools by the edges—they're very sharp. Consider wearing gloves to protect your hands.
Insert the iFlex at a downward angle between the bottom edge of the screen and frame.

Prying up the screen may take multiple attempts. If you're having trouble, apply more heat and try again.
With one hand, push down firmly on the watch's frame to secure it in place.
With your free hand, hold the iFlex and push the edges up to make it more rigid.
The iFlex should be slightly "U" shaped.
Pry up the screen enough for the iFlex to lay flat on its own.
The iFlex doesn't need to be inserted far, as it can easily damage the screen cables near the bottom right corner of the watch.
Leave the iFlex inserted under the screen.

Do not insert your opening pick more than 3 mm under the screen when separating the adhesive, as you risk damaging your watches internals.
Keep the iFlex flat to maintain a gap between the screen and frame while inserting an opening pick.
Insert an opening pick between the screen and iFlex.
Remove the iFlex.

Continue sliding your pick along the top edge and around the top right corner, stopping just after the digital crown.
Don't slide your pick past the digital crown—you risk damage to the screen cables.

Insert the long edge of an opening pick between the left edge of the screen and frame.
Twist the pick to lift the screen and separate any remaining adhesive.

Pull the right edge of the screen over the digital crown.
If the screen feels stuck, go back around it with an opening pick to separate any adhesive.
Swing up the left edge of the screen so it's upright. The screen should be to the right of the digital crown.
During reassembly:
This is a good point to plug in your watch and test all functions before sealing it up. Be sure to power it back down completely before you continue working.
Follow this guide to apply new screen adhesive and reseal your watch.
