Apple Watch SE – A2356 – MYEX2B/A

About this Apple Watch

The Apple Watch SE – A2356 watch was released on September 15, 2020, and is oriented toward the global market (except markets in the USA, Canada, Mexico, and Puerto Rico). This unit features high performance and a low price all at the same time. It does not have any advanced health sensors (except heart rate sensors and notifications) and is a little slower, but on the other hand, it can use an Internet connection and can also use a connection to an iPhone 6 or later (with IOS14 or later) in order to perform some additional functions.

The A2356 has a more than 30% larger display and is up to twice as fast as the Apple Watch Series 3. This watch uses the LTPO technology, providing less power consumption while the display is turned on and 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 an “Always on” Altimeter. The flash memory has 32GB, and 1GB of RAM is enabled for the user requirements.

The battery life is generally estimated at up to 18 hours, but it usually depends on specific usage. The aluminum case comes with many options, such as Silver with a White Sport Band or Deep Navy Sport Loop; Space Gray with a Black Sport Band or Charcoal Sport Loop; or Gold with a Pink Sand Sport Band or Plum Sport Loop. Also, many combinations are available from Apple via customization if needed.

Common questions

Is MYEX2B/A the same as A2356?

Not exactly. MYEX2B/A usually points to a specific retail configuration, while A2356 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Apple Watch is model A2356?

A2356 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 3488 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.
