Key Features and Benefits:

• Looks tough - because it is
  Titanium strikes the perfect balance between weight, ruggedness, and corrosion resistance. The case design rises up to surround the flat sapphire crystal and protect it from edge impacts. The Digital Crown is larger and the side button is raised from the case, making them easier to use while you're wearing gloves.
• Wayfinder watch face with Night Mode
  Specifically for Apple Watch Ultra, the Wayfinder face features a time dial that can be switched to a live compass and has room for eight complications. In low light situations, you can rotate the Digital Crown to activate Night Mode and see the watch face turn a vivid red.
• Ready for Action
  The Action button gives you quick, physical control over a variety of functions. It's customizable and can do things like control a workout, mark a Compass Waypoint, or begin a dive. Just like you, it's full of potential.
• Everything in its place
  An essential and versatile tool that fits on your wrist, Apple Watch Ultra packs incredible capability into a surprisingly small space.
• GPS antenna
  Precision dual-frequency GPS provides accurate location for calculating distance, pace, and route maps.
• Dual speakers
  A second speaker improves audio volume for calls and Siri.
• Depth gauge
  Provides real-time measurement of underwater depth down to 40 meters, along with water temperature readings.
• Three-microphone array
  In windy environments, an adaptive algorithm picks an excellent microphone for audio. Machine learning filters noise for optimal voice clarity.
• 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 longer battery life, you can take on almost anything and have energy to spare.
• Great training partner
  Whether it's your first run in a while, a 10K, or an ultramarathon, it takes a special kind of person to seek out challenges that test you physically. Apple Watch Ultra is the training partner to help you push your limits.
• Run like clockwork
  Measure your progress with extreme precision by customizing the Action button to control a workout, mark a segment, or move to your next interval.

  GPS performance is critical for athletes who want the most precise metrics, whether they're training in urban streets or out in the wild. Apple Watch Ultra features a precision dual-frequency GPS system that provides amazing accuracy in the most difficult locations.
• Comfort for the long run
  Designed to be light, thin, and flexible. It features a fuss-free loop closure for quick adjustments during workouts. Extra stretch built into the webbing makes it easy to cinch for optimal fit.
• The compass reimagined
  An accurate compass is as crucial for navigating the wild as a solid pair of boots. The redesigned Compass delivers views and functionality that take wrist-driven orienteering to greater heights.
• More information with every turn
  Start with a classic compass dial along with a constantly updating digital view of your bearing and direction. Zoom in by turning the Digital Crown and you'll see more on the giant display: elevation, incline, longitude, and latitude.
• Retrace your steps
  To help you return to where you came from, or simply get back on route, Backtrack uses GPS data to automatically create a path of where you've been - even if you're off the grid. So you can easily get to a previous location or all the way back down the mountain.
• 86-decibel Siren
  If you get lost or injured and need to attract attention, hold the Action button to activate a Siren that can be heard up to 600 feet or 180 meters away.
• Even in the sea
  Built to withstand jetskiing in Maunalua Bay or kitesurfing the Gorge. It delivers the data and functionality required by scuba and free divers for descents down to 40 meters.
