What’s your Apple Watch doing?

Find the symptom closest to yours: we tell you what it usually points to, what not to do in the meantime and which repair it belongs to.

The screen has lifted along one edge

What it usually is. Almost always a swollen battery pushing the glass out from inside. Apple acknowledged this as a defect on some models, but outside warranty the repair is replacing the battery and resealing the watch.

What not to do in the meantime. Don’t charge it and don’t wear it in the shower or the pool with the screen lifted: the seal is gone and water goes straight to the electronics. And don’t try to press it shut.

It won’t charge: no lightning bolt when I put it on the charger

What it usually is. Usually the charger itself or dirt between the puck and the back of the watch, but it can also be the charging coil or a battery that no longer takes a charge. Another charger and a clean back rule out half the cases.

What not to do in the meantime. Don’t leave it all night on a charger you already know doesn’t work, and don’t charge it with a wet strap or with sweat and sun cream on the back: that’s where corroded contacts come from.

The glass cracked in a knock

What it usually is. On the Apple Watch the glass, the touch layer and the panel are usually bonded into one block, and the watch is sealed against water on top of that. It can be replaced, but the seal has to be redone: it isn’t a matter of gluing on a piece of glass.

What not to do in the meantime. Don’t take it into water or wear it swimming until it’s fixed, and don’t put tape over the crack: the adhesive seeps into the break and makes the repair harder.

This is guidance based on the symptom, not a diagnosis: until the device is opened and measured, nobody can tell you for certain what’s wrong. The initial diagnosis is free and the quote is fixed before we touch anything.

What we repair

  • Screen replacement

    Cracked glass, a chipped corner, or a screen that has lifted away from the case. It’s opened with controlled heat, respecting the touch flex — one of the most fragile in Apple’s whole catalogue.

  • Battery replacement

    The watch doesn’t make it to bedtime, or dies when you use GPS. A swollen battery is also the usual reason a screen starts lifting on one side.

  • Won’t charge on the puck

    No reaction on the magnetic charger. It can be the charging coil, the battery or the board. We check before replacing anything.

  • Won’t turn on, or stuck on the Apple logo

    Software or a board fault. Diagnosed by measuring current draw and power rails.

  • Crown, side button and sensors

    A crown that turns with no effect, a sunken side button, a heart rate sensor that won’t read. We check whether the module or its connection is at fault.

  • Sealing and water resistance

    Any opening affects the factory seal. We reseal with fresh adhesive, but it’s worth knowing that a repaired watch isn’t equivalent to a factory one for water resistance.

  • Cracked glass even though touch still works

    The most common repair and the most postponed one. With the crack open, sweat and moisture reach the digitiser, so the assembly eventually fails and a simple repair turns into an expensive one.

  • Touch not responding, or the always-on display flickering

    Areas that ignore your finger, brightness that wanders, or a display that only half wakes. It can be the digitiser or its connector, and on a watch that connector is tiny: it gets checked under the microscope.

  • Won’t pair, or keeps losing the iPhone

    A watch that disconnects constantly, won’t sync, or never finishes pairing. With software ruled out it’s usually the antenna or its connection, often after a knock or a previous repair.

  • It got wet, or the sound is muffled

    The speaker ejects water, but sweat and seawater leave salts behind that corrode. If the sound is muffled or the watch took a proper soaking, opening, cleaning and resealing beats waiting to see.

  • Charging that stops, or a watch that gets hot

    Charging that starts and halts, heat in the case, or a watch that only charges in one exact position. We check the coil, the battery and the charging circuit before proposing anything.

  • A dented case and a chipped corner

    A knocked case leaves the glass sitting under tension, and a new screen on top of that breaks again soon. We assess it beforehand rather than fit a repair that’s doomed from the start.

  • The sensor crystal on the back has come away

    The sensor cover is glued to the case and lifts when the battery swells or the adhesive gives way. With that seal broken, sweat and moisture reach the board directly, so it’s worth sorting out early and resealing it with fresh adhesive.

  • A jammed band latch, or a band that won’t click in

    The release button won’t free the strap, or a new band rattles in the slot. We clean and check the mechanism in the case, which fills up with lint and sunscreen residue.

  • The heart-rate sensor takes no readings

    The watch logs no pulse and stops prompting workouts. We check the back crystal, its flex and the seal before replacing the sensor module.

Why many workshops won’t touch an Apple Watch

Everything inside an Apple Watch is small, glued and desperately short of space. The touch flex runs along one edge of the case and tears against a badly placed fingernail; the battery is bonded to the back; the seal has to be rebuilt from scratch. It’s a repair that rewards a steady hand, not force, and it doesn’t pay off for anyone working by volume.

The warning sign not to ignore

If the screen has lifted on one side, the adhesive hasn’t simply given up: it’s the battery swelling and pushing from within. From that point moisture and dust get in and the flex works under tension until it tears. Replacing the battery in time costs far less than replacing battery and screen together.

Board-level repairs

If the watch won’t power on, won’t charge or restarts on its own, the problem may be on the board. That’s where the microsoldering lab comes in: on a device this small, repairing the specific component is usually the only real alternative to binning it.

What the diagnosis covers

A watch gets checked as a whole before it’s opened, because it almost never arrives with just one thing wrong:

  • Glass and case: if the case is dented, new glass would sit under tension.
  • A lifted edge: when the glass has risen along one side, a swollen battery has to be ruled out before blaming the adhesive.
  • Battery: cycles and real capacity, not the impression that it lasts less.
  • Charging: tested with a reference puck and charger to separate the watch from the accessory.
  • Sensors, crown, button and microphone, plus the state of the seal inside whenever moisture is suspected.

That initial diagnosis is free. If the watch has to be opened and the board measured under a microscope, that’s an in-depth diagnosis: it carries a cost and you’ll know before we start.

If it has been wet

An Apple Watch handles water far better than a phone, but sweat, soap, chlorinated pool water and above all seawater leave residues that corrode from within. Don’t put it on the charger while wet, and bring it in if the sound goes muffled or the touch turns strange.

What the 12-month warranty covers

The repair comes with a 12-month warranty on the part we fit and on the labour. On an Apple Watch that means that if touch on the new screen fails, if dead areas appear, or if the battery we fitted degrades abnormally, it’s put right at no charge. The seal is rebuilt with fresh adhesive at every opening, but factory water resistance can’t be certified again: that falls outside the warranty, and we would rather say so beforehand than afterwards.

Is it worth repairing?

Almost always, if the model still receives updates: a battery replacement gives you back a perfectly usable watch for far less than a new one. For screens on older models we run the numbers with you first.

Models we work on

  • Apple Watch Series 11, 10, 9, 8 and 7
  • Apple Watch SE (all generations)
  • Apple Watch Ultra, Ultra 2 and Ultra 3
  • Apple Watch Series 6, 5, 4 and earlier
  • Apple Watch SE 3
  • Apple Watch SE 2

We’ve written separately about a few of these models, because there’s a quirk worth knowing before you repair them: Apple Watch Series 3.

    Super recomendable! Se me rompió el cristal de una de las cámaras traseras de mi iphone 14 pro, apple me pedía 600€ y ellos en un tarde me repararon dos cristales de las 3 cámaras por 70€. Los chicos muy agradables!

    Amazing service! They saved my laptop and stayed an hour after the closing hours to finish it just so that it would be ready the same day. Amazing people and service

Frequently asked questions

Is it worth repairing an Apple Watch?

Almost always, if the model still gets updates. A battery replacement gives you back a perfectly usable watch for far less than a new one. For screens on older models we run the numbers with you first.

Is it still water resistant after the repair?

We reseal it with fresh adhesive and it’s fine for everyday use, but we’ll say it plainly: no watch that has been opened keeps its factory rating. If you swim with it, bear that in mind.

The screen has lifted on one side. What’s that?

Nearly always a swollen battery pushing from the inside. It’s worth not using it like that: moisture gets in and the touch flex works under tension until it tears, which is what makes the repair expensive.

Will I lose my activity data?

No, as long as the watch is still paired with your iPhone. Health and activity data syncs to the phone. If you’re going to unpair it, let it finish the backup first.

How long does the repair take?

It depends on the model and on the part. We confirm the timeframe when we give you the quote, before you leave the watch with us.

What warranty does an Apple Watch repair carry?

12 months on the replaced part and on the labour for that repair, from the invoice date. If the same fault returns from the same cause we resolve it at no charge. A new knock or later water ingress are different faults.

Can just the glass be replaced on a watch?

On most models it doesn’t pay off: glass, digitiser and panel form a laminated assembly, and separating them needs specific machinery and carries a high risk of destroying the panel. Fitting the complete assembly is the usual and safer route.

Do you repair the Apple Watch Ultra as well?

Yes. The titanium case and the reinforced seal make opening it a different job, so it has to be taken even more slowly, but it’s a repair we do here like any other.

It went into seawater. Should I do something or wait?

Rinse it with fresh water, dry the outside, don’t charge it and bring it in. Salt is far more aggressive than tap water and keeps corroding even while the watch seems perfectly fine.

How long does an Apple Watch battery last before it needs replacing?

It depends on use, but there comes a point where the watch won’t last the day or dies during a workout or with GPS running. We check cycles and real capacity with the watch in front of us before recommending a replacement.

Can the crown be repaired if it turns without doing anything?

In many cases yes. We first check whether it’s debris packed around the shaft, which is fairly common, and if it isn’t, we assess the crown module or its connection to the board.

How much does an Apple Watch repair cost?

It depends on the model and the part. A battery and a screen are in completely different brackets, and on steel or titanium cases opening and resealing the watch is more delicate, which counts too. On an Ultra the screen assembly costs more than on an SE. You get a fixed quote before we open the watch.

My watch won’t charge on the magnetic puck. What could it be?

First we rule out the simple things: a known-good charger and cable, and a clean back with no dried sweat or sun cream on it. If it still doesn’t respond, the suspects are the charging coil, the battery and the charging circuit on the board. Only measuring tells them apart, because from the outside all three look identical.

My Apple Watch is stuck on the Apple logo and won’t start. What’s wrong?

Sometimes a restore from the paired iPhone sorts it out, so that’s the first thing to try. If the watch ends up stuck again, there is usually an unstable component on the board or a battery that can no longer deliver the current a start-up demands. We measure current draw and the power rails to tell which of the two it’s before suggesting anything.

What happens if the watch turns out to be beyond repair?

We tell you and give it back. Some damage, particularly after salt water or a hard knock to the case, is either not viable or not worth repairing, and we would rather say so than drag the job out. If the watch was still paired with your iPhone, your health and activity data isn’t lost: it lives on the phone.
