Apple Watch Series 7 (Edition, US/CA, 45 mm) Specs

About this Apple Watch

The Apple Watch Series 7 – Edition A2477 was released in September 2021 and is intended for sale in the US/CA market. It has a cellular and GPS connection installed. It can also (like a GPS-only model) be paired to an iPhone 6 that should be Series 6 or later (with iOS15 or later) to use the Internet and perform some additional functions. Compared to Apple Series 6 watches, the Edition A2477 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 critical 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.

This luxury watch is available only from Apple directly, and its housings are either silver Titanium or “Space Black” Titanium. Usually, there are three bands with Titanium, such as  purple “Leather Link”, orange “Leather Link”, and blue “Braided Solo Loop,” and two with Space Black Titanium — a blue “Solo Loop” and gray and black “Sport Loop.” Other watch bands are available through customization from Apple, as well.
