🔧 Repair Overview
Battery Replacement is one of the most common repairs for Withings ScanWatch. This repair involves replacing the damaged power component with a new or refurbished part. The process typically takes 30 min - 1 hour and requires moderate skill level.
What You'll Need
- Replacement power part (OEM or aftermarket)
- Precision screwdriver set (Phillips #000 or pentalobe)
- Opening tools (plastic spudger, suction cup)
- Adhesive strips or glue
- Clean workspace with good lighting
Step-by-Step Process
Step 1: Separate the Watch Face From the Case
The watch is held together by friction and a thin black seal—there are no screws.
Insert a thin metal smartphone opener between the ***metal case*** and the ***glass/display side*** of the watch (not the sensor side).
Carefully work your way around to loosen the seal.
The opening direction is often misunderstood—it’s from the face side, not the back sensor.
Step 2: Disconnect the Sensor Cable
Once the watch is open, you’ll see the movement and a small cable connecting the sensor to it.
This cable uses a connector similar to iPhones and can be released with a plastic spudger.
Gently pry the connector straight up to avoid damage.
Do not yank the cable. Always release the connector first.
Step 3: Inspect the Sensor Window (if Water Damage Suspected)
In this case, the condensation came from the ***glass above the sensor.***
From the inside, this glass popped out easily—suggesting poor or insufficient glue.
Clean the glass and sensor area thoroughly with isopropyl alcohol.
Re-glue the glass using a thin layer of T-8000 adhesive.
''Don’t apply too much glue—it can squeeze onto the sensor surface.''
Step 4: Free a Stuck Crown (Optional)
If your crown is stuck or hard to press, it may be repairable from the inside.
Add a ***small drop of penetrating oil*** (e.g. WD-40 or watchmaker’s oil) to the base of the crown from the inside.
This is optional and should be done with care.
Step 5: Battery Access (Advanced)
The battery can be replaced, but it's soldered to the board.
Requires soldering skills and proper tools.
This is not a beginner repair step and may damage the board.
Step 6: Reseal and Reassemble
Reconnect the sensor cable.
Make sure the ***o-ring seal*** sits completely in the corner of the metal ring
Snap the glass and ring back in with even pressure. This may require some force.
Clean any adhesive residue and allow glue to cure if used.
'' If the seal isn't seated properly, the watch won't fully close.''
