Apple Watch – A2376 – M09A3B/A

About this Apple Watch

The Apple Watch Series 6 – A2376 was released on September 15, 2020, for the Global market (except for the United States, Canada, Mexico, and Puerto Rico). It has cellular and GPS connectivity installed and can access the Internet without tethering through the iPhone. Anyhow, a connection to an iPhone 6 or later (with IOS14 or later) can be used to perform some additional functions. The A2376 has a more than 30% larger display and is up to twice as fast as the Apple Watch Series 3.

This watch uses LTPO technology to provide good visibility and a long-lasting screen, making it possible without too much battery power. The A2376 comes with a sensor that measures blood oxygen levels, known as an oximeter, which gathers information about breathing and blood circulation in 15 seconds, providing vital information about overall respiratory and cardiac health using the built-in Health application. In addition, there is an optical heart sensor and an application for the electrical heart sensor to detect irregular heart rhythms (ECG).

Apple LTPO technology is combined with an OLED screen which is, in addition, covered with Ion-X glass to enable scratch resistivity. The touch-capable display has a Digital Crown with haptic feedback and a screen with 368×448 pixels resolution and “Always on” capability. The flash memory has 32GB and 1GB of RAM. The battery life is generally estimated at 18 hours, but it usually depends on specific usage.

There were many (at least eleven) options related to colors and case-band combinations, such as Gold Stainless Steel with a Gold Milanese Loop, Blue Aluminum with a Deep Navy Sport Band, Gold Aluminum with a Pink Sand Sport Band, (PRODUCT) RED Aluminum with a Red Sport Band, Silver Aluminum with a White Sport Band, Dark “Space Gray” Aluminum with a Black Sport Band, Gold Stainless Steel with a Green Sport Band (pictured, left), Graphite Stainless Steel with a Black Sport Band (pictured, right), Graphite Stainless Steel with a Graphite Milanese Loop, Silver Stainless Steel with a White Sport Band, and Silver Stainless Steel with a Silver Milanese Loop. Also, many other body and watch band combinations were available from Apple on request.

Common questions

Is M09A3B/A the same as A2376?

Not exactly. M09A3B/A usually points to a specific retail configuration, while A2376 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Apple Watch is model A2376?

A2376 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 3482 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.
