Key takeaways
- Open the screen sideways like a book, without moving it more than a few millimeters to avoid tearing the extremely short flex cables.
- Heat the bezel to 90 °C and limit blade penetration to the edge to avoid cutting the Force Touch sensor on Series 1 to 5.
- Disconnect the battery before disconnecting or connecting the screen flex cables to prevent short circuits in the image circuits.
- Always check if the original detachment is due to a swollen battery before installing the new panel.
01 Diagnosis
Case Identification and Battery Inspection
The first step consists of identifying the case material and determining the true cause of the screen separation. On aluminum models, the glass used is Ion-X, while stainless steel and titanium cases feature sapphire crystal, with distinct part references.
- Confirm exact model and size in Settings > General > About
- Validate case material: aluminum (Ion-X glass) or steel/titanium (sapphire)
- Examine if the screen lifted due to impact or swollen battery pressure
02 Disassembly
Heating at 90 °C and Force Touch Preservation
Heat the watch perimeter to 90 °C to soften the factory sealing tape without damaging the OLED panel. The curved blade should penetrate only a fraction of a millimeter to cut the adhesive without reaching internal layers.

03 Electronics
Mandatory Battery Disconnection
The metal shield covering the connectors must be removed with a tri-point Y000 screwdriver before attempting to release any cable. Never handle the display connections with the motherboard powered.
After isolating the power supply, disconnect the screen flexors with fine tweezers or a plastic spudger. Clean old glue residue from the metal rim with isopropyl alcohol to ensure a perfect fit for the new part.
04 Workbench Mistakes
Mistakes We See Arrive at the Lab
Unsuccessful DIY repairs on Apple Watches arriving at the lab almost always share the same technical oversights.
- Blade inserted too deep, tearing the flex cables or the Force Touch gasket.
- Ordering screens of the wrong size, especially confusing 40 mm and 41 mm cases.
- Incomplete cleaning of the original adhesive, causing the screen to lift spontaneously after a few days.
- Assuming the device maintains factory water resistance after reassembly is complete.
05 Finalization
Assembly with New Gasket and Specifications
Always install a new cut-to-size adhesive gasket and test all panel functions before permanently gluing the watch. In the lab, we exclusively recommend Pulled or Refurbished screens to maintain the original response rate.
06 FAQ
Frequently asked questions
Is the Apple Watch still waterproof after the screen replacement?
No. Although a new perimeter adhesive gasket is applied, the watch loses its original factory sealing and should not be subjected to submersion.
Why did the screen start peeling off by itself?
In the vast majority of cases where the screen comes off without a drop, the cause is a swollen battery pushing the glass from the inside out, making battery replacement mandatory as well.
What is the most reliable type of screen for replacement?
We recommend original Pulled or Refurbished screens, which preserve the correct glass (Ion-X or sapphire) and prevent touch sensor failures.
Prefer to leave your Apple Watch with us?
We perform the complete screen replacement at the Micro Wire lab for €89.90 on the same day, using precision tools and with no risk to internal components.
