Repair Service
Cracked screen, dead battery, or water damage? Our specialists repair all major smartwatch brands — Apple Watch, Samsung Galaxy Watch, Garmin, Fitbit and more.
Apple Watch screen and battery repair in central London
We repair Apple Watch screens and batteries at two central London shops: 67 Marchmont Street in Bloomsbury (WC1N 1AP) and 16 City Road near Moorgate (EC1Y 2AA). Both are open seven days a week. Walk in or book online. Every watch gets a free diagnostic first, and if we can't fix it, you don't pay.
Apple Watch screen replacement starts from £49 and battery replacement from £35. We replace the cracked or dead display, then reseal the watch to restore its water resistance as closely as possible. Even so, avoid submerging it straight after a screen repair.
We work on Apple Watch from Series 3 to Ultra 2, including SE models, and also fix Samsung Galaxy Watch, Garmin, Fitbit and Huawei watches. For a less common model, call Bloomsbury on +44 7377 244454 before you travel so we can check the part is in stock.
If the watch has been in water, don't charge it and don't press the buttons. Bring it in as it is. The water-damage diagnostic is free, and the sooner we see it, the better its chances.
If you can't get to either shop, our free Pick & Drop service collects your watch from anywhere in London and brings it back once it's repaired.
