If you’re an Apple Watch owner, you might find yourself wondering exactly which model you have tucked on your wrist. With multiple generations and variations released over the years, identifying your Apple Watch model isn’t always as straightforward as it seems. Whether you’re looking to sell, upgrade, or simply learn more about your device’s capabilities, knowing your specific model is essential.

Understanding how to tell what model Apple Watch you have can unlock a wealth of information about its features, compatibility, and value. From subtle design differences to unique technical specifications, each model carries its own identity. This guide will help you navigate the process of identifying your Apple Watch with ease, setting the stage for informed decisions and a deeper appreciation of your wearable technology.

Before diving into the specifics, it’s helpful to grasp why model identification matters and what tools or methods can simplify the task. Whether you prefer checking physical details, using software settings, or referencing official Apple resources, there are several straightforward ways to pinpoint your watch’s exact model. Get ready to demystify your Apple Watch and discover exactly what you’re wearing.

Identifying Your Apple Watch Model Using the Back Case

One of the most straightforward methods to determine the model of your Apple Watch is by examining the information engraved on the back of the watch case. Apple typically includes a model number along with other specifications on the underside of the device.

Look closely for a small string of letters and numbers beginning with the letter “A” (e.g., A2351). This is the model number and is unique to each Apple Watch generation and variant. You can use this number to precisely identify your watch model.

To locate the model number:

  • Turn your Apple Watch over so you can see the back case.
  • Find the fine print etched around the sensor area.
  • Look for a model number starting with “A” followed by four digits.

Once you have the model number, you can cross-reference it with Apple’s official list or third-party resources to find the exact model and series.

Using the Apple Watch App on Your iPhone

If you have your Apple Watch paired with an iPhone, the easiest way to find the model is through the Apple Watch app. This method does not require inspecting the physical watch.

Steps to find your Apple Watch model via the app:

  • Open the Apple Watch app on your iPhone.
  • Tap on the “My Watch” tab at the bottom left.
  • Select “General” and then “About.”
  • Scroll down to find the “Model” field.

Initially, the model number displayed here begins with an “M.” Tap this number, and it will toggle to the “A” number, which is the standard model number used to identify your watch.

Using the Watch’s Settings Menu

If you cannot access the paired iPhone or prefer to check directly on the watch, you can find the model number through the watch’s settings.

To do this:

  • Press the Digital Crown to open the app grid or list.
  • Tap on the “Settings” app.
  • Navigate to “General” and then “About.”
  • Scroll to find the “Model” field.

As with the iPhone app, tapping on the model number will switch between the “M” number and the “A” number, the latter being the key identifier.

Below is a table with common Apple Watch model numbers and their corresponding series and case types. This will help you match your model number to the exact Apple Watch you own.

Model Number (A) Apple Watch Series Case Material Size (mm) Cellular Option

Additional Methods to Identify Your Apple Watch Model

Beyond the model number, other identifiers can help you determine your Apple Watch version:

  • Serial Number Lookup: The serial number can be used on Apple’s Check Coverage website to reveal the model and warranty status.
  • Watch Band Compatibility: Different Apple Watch models support specific band sizes. Knowing the band size can help narrow down the model.
  • Physical Features: Certain design elements such as screen shape, thickness, or presence of a red ring on the Digital Crown indicate cellular models and specific series.
  • Software Features: Some Apple Watch models support features like ECG or blood oxygen monitoring, which are limited to newer series.

By combining these clues with the model number, you can confidently identify your Apple Watch model.

Identifying Your Apple Watch Model Using the Back Case

The most straightforward way to determine your Apple Watch model is by examining the engravings on the back of the watch case. Every Apple Watch model has a unique model number inscribed, which can be used to identify the specific version.

  • Step 1: Turn your Apple Watch over to locate the engravings on the ceramic or sapphire crystal back.
  • Step 2: Look for a small text starting with the letter “A” followed by a four-digit number (e.g., A1975).
  • Step 3: Note this model number as it corresponds directly to a specific Apple Watch generation and case size.
Model Number (Back Case) Apple Watch Series Case Size Release Year
A1553 Apple Watch Series 0 (1st Gen) 38mm 2015
A1554 Apple Watch Series 0 (1st Gen) 42mm 2015
A1975 Apple Watch Series 4 44mm 2018
A1976 Apple Watch Series 4 40mm 2018
A2093 Apple Watch Series 5 44mm 2019
A2094 Apple Watch Series 5 40mm 2019
A2473 Apple Watch Series 7 45mm 2021
A2474 Apple Watch Series 7 41mm 2021

This method requires physical access to the watch, but it is the most accurate and easiest way to confirm your Apple Watch model.

Using the Apple Watch Settings to Find Model Information

If the back case is difficult to read or the watch is in use, you can also identify the model through the device’s software settings.

  • Step 1: Press the Digital Crown to access the Home screen.
  • Step 2: Tap on the Settings app.
  • Step 3: Scroll down and select General.
  • Step 4: Tap About.
  • Step 5: Look for the Model entry.

The model number displayed here may begin with an “M” or “N” (e.g., MKN02LL/A), which is a marketing part number. To convert this to the technical model number starting with “A”, tap on the model number once. It will switch to the “A” format, which matches the physical engraving on the back.

This method provides the model number without removing the watch or inspecting the case physically.

Checking Model Information via the Paired iPhone

Your iPhone paired with the Apple Watch can also provide model details through the Watch app.

  • Step 1: Open the Watch app on your iPhone.
  • Step 2: Tap the My Watch tab at the bottom.
  • Step 3: Select General > About.
  • Step 4: Scroll to find the Model entry.

Like on the watch itself, tapping the model number here toggles between the marketing part number and the technical model number starting with “A.” Use this number to reference Apple’s official model list or verify against known specifications.

Understanding Model Numbers and Apple Watch Generations

Apple Watch model numbers correspond with specific generations, case sizes, and features. Here’s how to interpret the model number:

  • “A” Series Number: The four-digit code beginning with “A” identifies the exact hardware model.
  • Case Size: Different model numbers indicate differing case sizes (e.g., 38mm, 40mm, 42mm, 44mm, 45mm).
  • Cellular Capability: Some models have cellular (LTE) support, often denoted by specific model numbers.
  • Material and Edition: Special editions (e.g., Edition, Nike, Hermès)
