Its standout feature is the ECG app, which is complemented by notifications for heart rate irregularities, making it a valuable tool for monitoring cardiac health. The watch also offers comprehensive fitness tracking, catering to a wide range of activities from cycling to yoga, and even includes specialized sensors for aquatic sports.

The design is sleek, with a larger, always-on Retina display that offers high visibility and clarity, and the watch is lightweight and comfortable to wear.

Compatibility is tailored for Apple devices, with seamless integration with iPhones from the XS model onwards, and additional features like Apple Pay enhance convenience. However, this limits use with non-Apple devices, potentially excluding some users who prefer other platforms. The watch also emphasizes safety with features like fall and crash detection, which can automatically alert emergency services. While the cellular variant provides independence from the phone, requiring a service plan might add to ongoing costs. The watch is robustly built, with crack and dust resistance, and comes with a range of customizable bands to suit various styles. Nonetheless, users should weigh the premium price against these features, especially if compatibility and battery duration are critical factors for them.
