Materials are a strong point, with aluminum construction, reinforced polymer, and Gorilla Glass repeatedly highlighted.
Materials are top-shelf throughout the reviewed models, with repeated praise for titanium and sapphire construction.
Menu navigation is mixed: buttons help, but several reviewers still found the menus hard to remember or counterintuitive.
Menu navigation benefits from a more organized structure, with reviewers specifically liking how key functions are surfaced more immediately.
Music controls are a useful smartwatch extra, but they are basic phone controls rather than a deeper audio feature set.
Music controls are functional and direct, including phone-music control from the watch.
Multiple reviews explicitly confirm there is no onboard or local music storage.
Onboard media support is strong, with local storage for music and podcasts plus service support for offline listening.
