Apple Watch Series 7 (Cellular, Global, 45 mm) Specs

About this Apple Watch

The Apple Watch Series 7 – A2478 watch was introduced in September 2021. The A2478 is present in the Global market, without the US/CA market. It has a cellular and GPS connection installed and can also (like a GPS-only model) be paired to an iPhone 6. The iPhone should be Series 6 or later (with IOS15 or later) to use the Internet and perform additional functions. Compared to Apple Series 6 watches, the A2478 offers a larger, more durable display and faster charging. With the LTPO technology, the LTPO OLED retina display features an “Always-On” capability and 1000 nits of full brightness.

There are four main health features of the Apple Watch Series 7. Apart from the heart rate notification, there is also a very important Irregular Heart Rhythm notification, Blood Oxygen application, and ECG application. The LTPO technology enables the “Always on” ability and keeps the battery alive for up to 18 hours. On the other hand, battery life varies by use, cellular coverage, configuration, and many other factors, so the actual results will vary.

The case size is 45 mm and features a 396×484 pixel LTPO OLED screen covered with Ion-X glass to enable scratch resistivity. It is a touch-capable display with a Digital Crown with haptic feedback and an “Always on” Altimeter. The haptic feedback for the Digital Crown gives users a more tactile experience while scrolling through the content.

The 32GB of flash memory and about 1GB of RAM support all the main user requirements. The battery life is generally estimated at 18 hours, but it usually depends on specific usage.

There are a lot of case-band combinations related to this watch. For the aluminum case, the colors are Green, Blue, Starlight, Midnight, and Red (product color). For the stainless-steel case, the colors are  Graphite, Silver, and Gold, and for the titanium case, the colors are Space black and Titanium.
