Xiaomi Black Shark GS3 Ultra Display and Design
The Black Shark GS3 Ultra is built around a 1.43-inch AMOLED panel with a 466×466 pixel resolution, delivering sharp, vivid visuals even in bright outdoor conditions thanks to its 1,000-nit peak brightness. The watch ships in two colour options — black and silver — giving it a versatile look that works for both workouts and daily wear. Over 270 free watch faces are included out of the box, so personalisation is effortless.
As an upgraded successor to the original Black Shark GS3, the Ultra model refines the overall package with enhanced durability. It carries a 5ATM water-resistance rating, meaning Xiaomi certifies it safe for immersion up to 50 metres. Whether you are swimming laps or caught in a downpour, the watch is built to handle it.
