Apple Watch Series 7 – A2476 – MKJ33B/A

About this Apple Watch

The Apple Watch Series 7 – Nike A2476 watch was released in September 2021 and sold in the Global market (except the US/CA market). This is a cellular model, and it does not require the iPhone to use Internet functions. However, a connection to an iPhone 6 or later (with iOS15 or later) enables the user to perform additional functions.

The Nike Run Club offers more Guided Runs and supports to enhance runners. At the same time, this watch offers very important health notifications, such as Heart Rate notifications, Irregular Heart Rhythm notifications, Blood Oxygen applications, and ECG applications. Compared to Apple Series 6 watches, the Series 7 offers larger, more durable displays and faster charging.

The LTPO technology provides the LTPO OLED retina display, enabling an “Always-On” capability and 1000 nits of full brightness. 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 41 mm and features a 352×430 pixels 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 user requirements. The battery life is generally estimated at up to 18 hours, but it usually depends on specific usage.

There are two aluminum case options for the Nike A2475: a warm gray “Starlight” with a Platinum/Black Sport Band and a nearly black “Midnight” with an Anthracite/Black Sport Band. Also, there are a lot of body-band customized combinations available from Apple.

Common questions

Is MKJ33B/A the same as A2476?

Not exactly. MKJ33B/A usually points to a specific retail configuration, while A2476 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Apple Watch is model A2476?

A2476 is the Apple A-number shown for this Apple Watch family. Use the order number, EMC, and model identifier on this page to narrow the exact configuration.

What does EMC 3984 mean?

The EMC number is another Apple hardware identifier. It helps separate closely related models that may share a similar name, year, or A-number.

Can the RAM or SSD be upgraded?

Check the spec table for the exact configuration. Many newer Apple Silicon Macs have memory and storage integrated into the board, so RAM and SSD upgrades are often not practical after purchase.

What macOS versions work with this model?

Use the model identifier, release year, and processor family from the spec table when checking macOS compatibility. Compatibility can change as Apple releases new macOS versions.

Is this Apple Watch still worth buying used?

It can be, depending on price, battery health, memory, storage, and condition. Compare this exact order number and model identifier against similar Techable listings before buying.

How much is this Apple Watch worth?

Value depends on RAM, storage, battery health, cosmetic condition, accessories, and market demand. Use the SellMac path on this page for a quote or use the identifiers here when comparing resale prices.

What should I search if this page is not the exact configuration?

Search the order number first when available, then compare the A-number, EMC, model identifier, year, chip, RAM, and storage. The same A-number can cover more than one configuration.
