Introduced as a "budget" option alongside the Apple Watch Series 6, the Apple Watch SE have more in common with the Apple Watch Series 5 replaced, but lack its predecessor's "Always On" display as well as its electrical heart sensor and ECG app (they do have an optical heart sensor). Compared to the more expensive Apple Watch Series 6, the Apple Watch SE line shares its always-on Altimeter, but is slower, lacks its Blood Oxygen sensor (SpO2) and app, has less capable Wi-Fi, and charges more slowly. It only is available in Aluminum and has fewer finish options and fewer default band choices, too.

All cellular-equipped Apple Watch SE models, including this one, are capable of being connected to the Internet without a "tethered" iPhone, but it still requires an iPhone 6s or later running iOS 14 or later for most functionality.

All Apple Watch SE devices are controlled with a Digital Crown with haptic feedback and a touch capable display. This particular Apple Watch SE model in the 40 mm size, features a 324x394 LTPO OLED screen with Ion-X glass packed in an aluminum case with a ceramic and sapphire crystal back that connects to the charger.

Battery life is an Apple estimated "up to 18 hours" overall, but more specifically "up to 1.5 hours" of talk time connected to an iPhone or LTE, "up to 10 hours" of audio playback from Apple Watch storage, "up to 10 hours" working out indoors and "up to 6 hours" working out outdoors with GPS.

There were at least six aluminum options available from Apple Authorized Resellers -- Gold with a Pink Sand Sport Band or Plum Sport Loop; Silver with a White Sport Band or Deep Navy Sport Loop; and Space Gray with a Black Sport Band or Charcoal Sport Loop. A variety of other body and watch band combinations were available from Apple via customization, as well.
