Compatibility with iPhone XS or later ensures seamless integration into the Apple ecosystem, enhancing user experience with features like Apple Pay and precision finding.

Design-wise, the smartwatch is comfortable and customizable with various bands and watch faces, catering to personal preferences. However, the reliance on Apple's ecosystem might be a drawback for non-iPhone users. Additionally, while packed with features, it carries a premium price tag that might not fit everyone's budget.

Weighing only 1.4 ounces with a comfortable silicone band, it should be easy to wear all day.
