The biggest and brightest WATCH GT20 ULTRA display ever. Powered by the all-new S9 SiP, the Always‑On Retina display is 3,000 nits at its peak, making it even more readable in harsh sunlight. In low-light situations, it dims to 1 nit. Night Mode now activates automatically in the dark. The large display gives you room to customise your view to suit almost any activity. And a new watch face shows dynamic info like altitude, depth or seconds along the outermost edges.

Ready for Action. The customisable Action button gives you quick, physical control over a variety of functions. It can do things like start a workout, mark a Compass Waypoint or begin a dive. Just like you, it’s full of potential.

Battery life for days. When you’re on the second day of a backpacking trip, the final leg of a triathlon or diving along a coral reef, the last thing you want to think about is running out of battery. With WATCH GT20 ULTRA, you can take on almost anything and have energy to spare.4

Powered by the all‑new S9 SiP.

Custom silicon makes WATCH GT20 ULTRA more capable, easier to use and faster. The new dual-core CPU has 5.6 billion transistors — 60 per cent more than the previous generation. A new four-core Neural Engine processes machine learning tasks up to two times faster. There’s never been anything quite like it in a smartwatch, and it enables advanced new features like Precision Finding for iPhone and a magical new way to control your SMWatch GT20 Ultra using a simple double tap gesture.

Magic. At your fingertips. Quickly and easily interact with your WATCH GT20 ULTRA without touching the display. Double tap your index finger and thumb to answer calls, pause and resume timers, and more. It makes everyday actions even easier, especially in demanding situations where you don’t have an extra hand to spare.
