Apple Watch Ultra Gps + Cellular, 49MM- Medium MQFR3AE/A

The Apple Watch Ultra tracks movement throughout the day like other Apple Watch models, keeping track of steps taken, calories burned, and workouts. It provides exercise, movement, and stand rings in the Activity app, and offers up reminders to help people get out and move more often.

Apple created a Depth app for the Apple Watch Ultra that uses a depth gauge when under water. The Depth app can display the time, current depth, water temperature (using the Apple Watch temperature sensor), the duration spent under the water, and the max depth reached.

As it has a larger case size, the Apple Watch Ultra can accommodate a larger battery that lasts for up to 36 hours. The Apple Watch Ultra is equipped with a 542 mAh battery, which is 76 percent larger than the 308 mAh battery that's in the 45mm Apple Watch Series 8.

With Low Power Mode and an additional battery savings option that cuts down on heart rate measurements during workouts, the Apple Watch Ultra's battery can last for up to 60 hours for multi-day adventures.

The Apple Watch Ultra supports fast charging technology and comes with an Apple Watch charging puck that allows for quicker charging speeds. The charging puck has an exclusive upgraded braided cable that is not available with other Apple Watch models

The aerospace-grade titanium case strikes the perfect balance of weight, durability and corrosion resistance.

The Ocean Band is moulded in a high-performance elastomer with a tubular geometry allowing it to stretch for a perfect fit, even over a wetsuit. The titanium buckle and adjustable loop secure the band during high-speed water sports.

Apple Watch bands are available in a variety of styles and sizes.

First, you’ll need to choose a case size and band style to see which band sizes are available with that combination. The band you choose will specify the maximum and minimum wrist size. To get the correct band size, we recommend that you precisely measure around your wrist.

If you choose a Solo Loop band, you’ll need to use the sizing guide to find your exact size. When you shop for Solo Loop bands, there are step-by-step instructions to help you measure your wrist using a printable tool or household objects so you can find the correct size.
