The Apple Watch Ultra 4 is built for mountains, sea and mud, but even sapphire glass can crack from a hard knock against a rock or a dumbbell, and long GPS training sessions place heavy demands on the battery. FIXNOW replaces the glass or the full screen, the battery, the back glass with its sensors, and the Digital Crown or side button of your Ultra 4. Stop by in Antwerp or Wolvertem, or send in your Apple Watch through our shipping service.

What owners of the Apple Watch Ultra 4 49mm come to us for

The Apple Watch Ultra 4 is built to take a knock: sport, diving, a rough working day outdoors. That very use is what causes the complaints that come in. The sapphire glass is strong, but a hard knock against stone or metal can still leave it with a scratch or a crack.

  • Scratch or crack in the sapphire glass after an impact
  • Side button that sticks after sand or seawater
  • Battery that does not last as long as expected with intensive use
  • Digital Crown or side button that no longer works smoothly

Apple Watch Ultra 4 49mm: glass polishing and battery replacement

Light scratches in the sapphire glass of your Apple Watch Ultra 4 we polish away at FIXNOW, without replacing anything. If the glass is genuinely cracked after a hard knock, we first take a look at the device: sapphire is hard, but not unbreakable, and not every crack can be fixed in the same way. Diagnosis is free when we carry out the repair, so you know in advance where you stand.

We replace the back with the sensors separately from the rest of the device if it is damaged or loose. If the Digital Crown turns stiffly or the side button sticks after sand or water, we make it smooth again.

The large battery of the Ultra 4 is made for long use outdoors, but that battery too eventually loses capacity. We fit a new one in your own titanium case. In Antwerp and Wolvertem we take the time needed for this; if you live further away, the device can also be sent in.

Heel tevreden over Fixnow Wolvertem! Vriendelijke en efficiënte service. De batterijen van twee iPhones werden binnen het afgesproken uur vervangen. Alles verliep snel en correct. Zeker een aanrader!

Had al een tijd last van een slecht werkende USB-C poort. De vriendelijke shopkeeper heeft gratis de poort kundig schoongemaakt waardoor ik geen problemen meer met opladen heb. 5/5!
