AvatarByArmando Lewellen Smartwatches

If you’ve ever found yourself wondering, “How do I tell what Apple Watch I have?” you’re not alone. With multiple models released over the years, each boasting unique features and design tweaks, identifying your specific Apple Watch can sometimes feel like a puzzle. Whether you’re looking to sell your watch, upgrade your accessories, or simply satisfy your curiosity, knowing exactly which model you own is the first step.

Understanding which Apple Watch you have goes beyond just the name on the box. From the original Series 0 to the latest iterations, Apple has introduced various sizes, materials, and functionalities that can make distinguishing between models tricky. Fortunately, there are straightforward ways to pinpoint your watch’s identity using both physical characteristics and software details.

In the following sections, we’ll explore simple methods to help you accurately identify your Apple Watch model. By learning these techniques, you’ll gain confidence in recognizing your device and better appreciate the technology on your wrist. Whether you’re a seasoned Apple enthusiast or a new user, this guide will equip you with the knowledge you need to know your Apple Watch inside and out.

Using the Model Number to Identify Your Apple Watch

Every Apple Watch has a unique model number that provides precise information about its series, size, and cellular capabilities. Locating and interpreting this model number is one of the most reliable methods for identifying your specific Apple Watch.

To find the model number on your Apple Watch, follow these steps:

  • Open the Settings app on your Apple Watch.
  • Tap General.
  • Select About.
  • Scroll down to find the Model field.

Initially, you will see a part number that begins with an “M” or “N.” Tap this number once, and it will change to the model number, which starts with an “A” followed by four digits (e.g., A1975).

Once you have the model number, cross-reference it against the following table to identify your watch’s generation, case size, and cellular capability:

Model Number Apple Watch Series Case Size Cellular (LTE) Option
A1553 Series 0 (1st Gen) 38mm No
A1554 Series 0 (1st Gen) 42mm No
A1757 Series 1 38mm No
A1758 Series 1 42mm No
A1860 Series 3 38mm Yes
A1861 Series 3 42mm Yes
A1975 Series 4 40mm Yes
A1976 Series 4 44mm Yes
A2092 Series 5 40mm Yes
A2093 Series 5 44mm Yes
A2351 Series 6 40mm Yes
A2352 Series 6 44mm Yes
A2473 Series 7 41mm Yes
A2474 Series 7 45mm Yes

Knowing the model number also helps distinguish between GPS-only and GPS + Cellular models. Typically, the cellular versions have additional hardware components and thus a different model number than their GPS-only counterparts.

Identifying Your Apple Watch by Physical Characteristics

If accessing the model number on the device is inconvenient, you can also identify your Apple Watch by examining its physical characteristics. Apple has made several design changes through the generations that can help you determine which model you own.

Consider the following:

  • Case Size and Shape:

Earlier models (Series 0 to Series 3) used 38mm and 42mm cases. Starting with Series 4, Apple introduced larger case sizes (40mm and 44mm) with slimmer bezels and more rounded corners. Series 7 and later further increased the screen size to 41mm and 45mm with thinner borders.

  • Back Material:

The first three series used ceramic and sapphire crystal backs, while Series 4 and newer models switched to a ceramic and sapphire crystal combination with a more seamless design.

  • Display Type:

Series 5 and later introduced an always-on Retina display, which remains visible even when your wrist is down.

  • Digital Crown:

From Series 4 onward, the Digital Crown features a red ring for cellular models instead of a solid red dot seen in Series 3 LTE models.

  • Sensors and Features:

Series 4 added the electrical heart sensor enabling ECG capabilities, which is absent in Series 3 and earlier models.

These physical cues can be used alongside the model number to confidently identify your Apple Watch.

Checking Your Apple Watch via the Paired iPhone

Your paired iPhone provides an easy way to identify the Apple Watch model if you prefer not to use the watch itself.

To find your Apple Watch model through the iPhone:

  • Open the Watch app on your iPhone.
  • Tap the **My Watch

Identifying Your Apple Watch Model Through Physical Characteristics

To determine which Apple Watch model you own, start by examining the physical features of the device. Apple has released multiple generations and variations with distinct design elements. Key aspects to check include:

  • Case Size: Apple Watch sizes have evolved. Early models offered 38mm and 42mm cases, while newer ones come in 40mm, 44mm, 41mm, or 45mm.
  • Material and Finish: The case material varies by model and edition:
  • Aluminum (standard models)
  • Stainless steel (higher-end models)
  • Titanium (Apple Watch Ultra and some SE editions)
  • Display Characteristics: Newer models feature edge-to-edge displays with thinner bezels.
  • Button Layout and Features:
  • The Apple Watch Ultra includes an additional Action button on the left side.
  • Some models have different speaker grille designs or microphone placements.

By closely comparing these physical features to official Apple specifications or comparison guides, you can narrow down your model.
