The Ultra 3 is the biggest, most powerful, and priciest Apple Watch. It’s priced more like an iPhone than an Apple Watch, but it works hard to justify its cost. It has the longest battery life of the line, lasting nearly three full days on a charge in the real world. Plus, 5G comes standard on the Ultra 3 for fast downloads when you’re away from your phone, and it’s the only Apple Watch with satellite connectivity. If you’re adventuring out of cell service range, you can use satellites to contact emergency services, send texts, and keep your loved ones up to date with your location.
Additionally, the Ultra 3 is much more durable than its siblings and can withstand extreme temperatures, deep submersion, and high altitudes. It also has a superior altimeter, depth gauge, and GPS antenna than the Series 11.
Since it matches the Series 11 in exercise monitoring and lifestyle features, you probably don’t need to pay the premium for the Ultra 3 for day-to-day activities, but it’s worth the money if you’re into mountain biking, water sport expeditions, or other adventurous activities.
