Apple Watch Series 3 38 mm Cellular(International) Specs

About This Watch

The Apple Watch Series 3 is almost identical in its shape and form to its predecessors but has been fitted with upgraded and more powerful internals. Whilst the battery and many other components stayed the same, the most notable upgrades are the new Apple S3 processor and the ability for certain watches to be connected to a 3G network. This allows for the watches to be fully functional without needing to be tethered to an iPhone. This functionality is not present in the GPS only variants but is present on the cellular variants. The watches function off a partnered SIM card which needs to be purchased with the same mobile carrier as your phone.

Common questions

Is MQKF2B/A the same as A1889?

Not exactly. MQKF2B/A usually points to a specific retail configuration, while A1889 identifies the broader Apple hardware family. Always check the EMC and model identifier too.

What Apple Watch is model A1889?

A1889 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 3169 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.
