Check the back of your Apple Watch: The case back lists the series name, size, material, water resistance, and depth rating, helping you quickly confirm your model.
Check the original box for model number and specs: The box label shows your Apple Watch’s series, serial, IMEI, region, and band variant, offering the most accurate identification.
Use iPhone settings to identify your Apple Watch: Open Settings > Apple ID > your Apple Watch to see the model, serial, and version for quick verification.
Confirm if your Apple Watch is original: Enter your serial number on checkcoverage.apple.com to verify authenticity, warranty status, and purchase details.
Check if your Apple Watch is refurbished: The model number prefix reveals its status—M for new, F for refurbished, or N for an Apple replacement.
Unless you compare them side by side, almost all the latest Apple Watch models look nearly identical at first glance. That’s why when you’re buying new bands, selling a pre-owned watch, upgrading to watchOS 26, or troubleshooting, you may wonder: “Which Apple Watch do I have?”
This guide shows you three simple ways to identify your Apple Watch model, plus a bonus tip to verify if your Apple Watch is original. Let’s dive in.
Here are three reliable methods: the first two are fast, the third gives the full technical breakdown about model number, case size, origin, and more (useful for accessories, trade-in, repair, etc).
1. Check the Back of Your Apple Watch
Flip over your watch and look for the engraving on the case back. Most models will have:
Series name (e.g., “Watch Series 11”, “Watch Ultra”, “Watch SE”)
Case size (e.g., 42 mm, 46 mm, 49 mm)
Materials (Aluminum, Stainless Steel, Titanium)
Connectivity type (GPS or GPS + Cellular)
Water resistance rating
Maximum depth
So if you see a 49 mm Titanium case and “Watch Ultra” on the back, you’re likely dealing with “Ultra” model (and could be the new Ultra 3 or earlier Ultra). For Series 11 you’ll see that series name rather than “Series 10”.
With this information, you will be able to find the right Apple Watch accessories, software, and services for your wearable.
2. Check the Original Box for the Model Number & Specs
If you still have the original packaging, the back label is very informative. You’ll find:
Series name & case size
Model number (starts with “Axxxx”)
Serial number, IMEI/EID if Cellular model
Band size/type
Region / variant information
Once you have the model number, you can compare it to the reference list below to identify exactly which Apple Watch variant (region, GPS vs Cellular, size) you have.
