The Apple Watch Ultra 2 is strictly available only in premium plans. Macworld gives a concise expert overview. Positives include its vivid display, fluid functioning operating system, and commendable workout tracking. However, on the downside, it works solely with iPhones, lacks as many fitness parameters as other competitors, and its topographical maps only cover the US territory.

While it doesn't bring many noticeable technological advancements over the original, thus not making it a worthy upgrade, it warrants praise as an exceptional smartwatch with considerable battery life. The base price at review was $799. Various retailers are offering discounts, with some selling it for as low as $749.

The Apple Watch Ultra is fashioned for thrill-seekers and sports lovers who require a sturdy, long-lasting smartwatch capable of enduring extreme conditions. Beyond this, it has gained popularity amongst the general public largely due to its impressive aesthetics and significantly extended battery life compared to the standard Apple Watch.

Design-wise, it boasts a 49mm, 3000-nit OLED display with an ambient light sensor and a second-generation ultrawideband chip. Its health and fitness tracking capabilities are diverse and high-quality, including metrics for heart rate, sleep patterns, etc., powered by Apple’s S9 chipset. It mirrors the same tracking capabilities as the Watch Series 9.

The Apple Watch Ultra 2 incorporates several unique features for hikers, divers, and other athletes, targeting specific needs like depth tracking for divers or GPS tracking for outdoor workouts. The durability and water resistance make it a reliable outdoor companion.

Alongside outdoor-centric features, the Watch Ultra 2 also enables comprehensive health monitoring, including sleep quality, heart rate, etc. However, these data don't serve medical purposes, but are highly accurate, primarily for heart rate.

The Apple Watch Ultra 2 initially costs $799. One of its main advantages is its extended battery life, allowing up to 3 days of usage when used judiciously. It remains a highly recommended smartwatch option, albeit with minor improvements over the previous Ultra. Apple Watch Ultra 2 thus stands out as Apple's most accomplished smartwatch, although not significantly superior to the original Ultra.
