Apple Watch - Series 8 Screen Replacement

Introduction

Use this guide to replace a broken, cracked, or defective screen on your Apple Watch Series 8.

It is possible to replace the screen of the Apple Watch Series 8 without removing or disconnecting the battery first. However, this can lead to a malfunction of the NFC antenna under certain circumstances. If you feel comfortable with your repair, skip the battery removal steps in this guide. Otherwise, follow this guide in it‘s original order.

Replacing the display can cause issues with Apple Pay. If possible, to reduce the likelihood of problems, delete all your Apple Pay account info before the replacement, and then re-enter it with the new display installed.

This guide shows the procedure on the 45 mm cellular/LTE version of the watch, but the GPS-only version is similar.

You’ll need replacement adhesive to reattach the battery and the screen when reassembling the device.

    • Because the gap between the screen and watch body is so thin, an iFlex is needed to separate the two.

    • Protect your fingers by keeping them completely clear of the iFlex edge. If in doubt, protect your free hand with a heavy glove, such as a leather shop glove or gardening glove.

    • Be careful not to apply too much pressure, as this might cause the iFlex to slip and cut you, or damage the watch.

    • Wear eye protection. If the opening procedure is performed incorrectly or with too much pressure, the glass could crack, sending small glass shards flying.

    • Attach or remove the watch band as needed to provide more control as you make repairs.
