How to Tell Which Series Your Apple Watch Is: A Simple Guide

How To Tell Which Series Apple Watch: Shopping for the latest Apple smartwatch but lost in the variety? Figuring out how to tell which series Apple watch you’re choosing is a common conundrum. In fact, 60% of consumers find it difficult to identify the different Apple Watch series according to a recent 2022 report by Statista. This can lead to quite a bit of confusion when selecting the perfect series for your requirements. Look no further, as this guide addresses your queries.

Identifying Your Apple Watch Series

Knowing your Apple Watch series is more important than you might think. It’s not just about bragging rights or knowing which shiny new features you have access to. It’s about compatibility with apps, watch bands, and even iPhone models. Plus, if you ever need technical support or repairs, the first thing you’ll be asked is, “What series is your Apple Watch?”

Now, you might be thinking, “They all look the same, how am I supposed to know?” Well, each series has subtle differences. For example, the Series 3 has a composite back, while the Series 4 and later have a ceramic and sapphire crystal back. The Series 5 introduced an always-on display, and the Series 6 brought blood oxygen monitoring into the mix. You can learn more about these differences in our article, How to know what Apple Watch series I have.

Using the Model Number

One of the easiest ways to identify your Apple Watch series is by using the model number. You can find this number in two places: on the device itself and in the Apple Watch app on your iPhone.

To find the model number on your watch, turn it over and look for the small text around the circular heart rate sensor. You’ll see ‘Model’ followed by ‘A’ and four digits. Now, this is where it gets a bit tricky. The model number on the device starts with ‘A’, but you’ll need the one that starts with ‘M’ or ‘N’ to identify the series.

Don’t worry, you don’t have to go on a wild goose chase. Just open the Apple Watch app on your iPhone, go to ‘My Watch’ tab, tap ‘General’, then ‘About’. Here you’ll find the model number that starts with ‘M’ or ‘N’. Tap on it, and it will change to a five-character SKU. The first character of the SKU indicates the series and material of your Apple Watch.
