Apple Watch SE (All Versions): Overview and Specifications. The Apple Watch is a line of smartwatches developed and marketed by Apple. It has fitness tracking, health-oriented capabilities, and wireless telecommunication, integrating with watchOS and other Apple products and services. The first Apple Watch was released in April 2015,[4][5] and quickly became the world’s best-selling wearable device. 4.2 million were sold in the second quarter of fiscal 2015,[6] and more than 115 million people were estimated to use an Apple Watch as of December 2022.[7] Apple has introduced a new generation of the Apple Watch with improved internal components each September[8] – each labeled by Apple as a ‘Series’, with certain exceptions.[a]

Each Series has been initially sold in multiple variants defined by the watch casing’s material, colour, and size (except for the budget watches Series 1 and SE, available only in aluminium,[9][12] and the Ultra, available only in 49 mm titanium[11]), and beginning with the Series 3 and Series 11, by the option in the aluminium variants for LTE and 5G cellular connectivity, respectively, which comes standard with the other materials.[13][14] The band included with the watch can be selected from multiple options from Apple, and watch variants in aluminium co-branded with Nike and in stainless steel co-branded with Hermès are also offered, which include exclusive bands and colours. Any user may use digital watch faces carrying those companies’ branding.[13]
The Apple Watch operates in conjunction with the user’s iPhone for functions such as configuring the watch and syncing data with iPhone apps, but can separately connect to a Wi-Fi network for data-reliant purposes, including communications, app use, and audio streaming.[15][16] LTE and 5G-equipped models can also perform these functions over a mobile network, and can make and receive phone calls independently when the paired iPhone is not nearby or is powered off.[b] The oldest iPhone model that is compatible with any given Apple Watch depends on the version of the operating system installed on each device.[19] As of September 2025, new Apple Watches come with watchOS 26 preinstalled and require an iPhone running iOS 26, which is compatible with the iPhone 11 or later.[20][21]
The Apple Watch is the only smartwatch fully supported for the iPhone, as Apple restricts the APIs available in other smartwatches, so other smartwatches always have less functionality.
