Apple Watch Ultra 4

Apple Watch Ultra 4 drops to $699.99, its lowest price yet

Fifty hours of battery on a smartwatch is the kind of number that makes you check the spec sheet twice. Apple's Ultra 4 promises exactly that, double the Series 12, and right now it's $699.99 at Amazon, a $100 drop that matches its lowest price yet. The S11 chip brings Sound Recognition and a Live Rewind feature that replays the last 15 seconds of a conversation you were physically present for, which is either wonderful or mildly terrifying depending on the conversation. The Readiness score crunches sleep and activity into a zero-to-10 verdict on whether to push or rest. It's still rugged, still bright, still IP6X. If you're weighing the upgrade, our hands-on impressions are worth a read before you commit.
