If you want a giant smartwatch that lasts all weekend, the Apple Watch Ultra 3 is your best choice. But if you’re willing to sacrifice a little battery, you can get an Apple Watch Ultra 2 instead, which has the same design, nearly identical display, and most of the same features. And today, Amazon has one on sale for $549, a savings of $250 and the best price we’ve ever seen.

With built-in GPS and cellular connectivity, the Apple Watch Ultra 2 keeps you connected to the world even without your phone nearby. That makes it ideal for hiking and swimming, with military-grade MIL-STD 810H and water resistance up to 100m. It’s also got a heart-rate sensor, blood-oxygen, ECG, and body temperature, as well as hypertension and sleep apnea alerts. And of course, you can use it to make calls, send messages, and receive notifications.

In our 4-star review of the Ultra 2, we praised the large screen and rugged design as well as the battery life, which we found to last at lest two days, about as long as the Ultra 3’s 42-hour rating. So go snag this Apple Watch Ultra 2 for $549 before Amazon’s stock dries up.
