The Apple Watch Ultra is a brand-new and totally different design for the adventurer. The new larger 49mm watch case is made of durable aerospace-grade titanium that houses a sapphire crystal screen. At 2000 nits, it's twice as bright as any other model so far. The Apple Watch Ultra has a new button on the opposite side of the Digital Crown called the Action button. You can customize that button to do various things, such as start a workout or move to the next interval of a custom workout in watchOS 9. The digital crown and side button are also different; there's a raised lip around them both, and they are textured to allow use while wearing gloves. The Apple Watch has a host of other new features, such as resistance to temperature extremes, deep-water water resistance, bigger speaker, longer battery life, and more.

Will my old bands fit the Apple Watch Ultra?

Even though the watch case itself is quite a different size and shape, the band slots remain the same as all of the larger Apple Watch models. So yes, the Apple Watch Ultra can use your old bands. As long as your bands are made for the 44mm or 45mm Apple Watch models, bands are interchangeable.
