There are now apple watch models on the market: the original series 1, series 2, and the all-new series 3. If you’re not sure which model you have, this guide will help you identify it.

The obvious place start is by looking at the back of your watch. If it has a red stripe, it’s a series 2. If it doesn’t, it’s either a series 1 or series 3.

To tell them apart, you’ll need to look at the model number on the back of the watch. It’s located just below the “iWatch” moniker. If the model number starts with “MNNN,” it’s a series 1. If it starts with “NNNN,” it’s a series 3. The older model numbers are eight digits long, while the newer ones are ten digits long.

If your watch is an older model and you can’t find the red stripe or model number on the back, don’t worry—you can still identify it using Apple’watch app for iPhone. Just open up the app and go to “My Watch > General > About.” The first line will tell you which model you have.

The Different Models apple watch

The Apple Watch comes in different models, sizes, colors, and materials. There are three main types of Apple Watches: the Sport, the Edition, and the regular Watch. And within those categories, there are subcategories that make up the different models. So which Apple Watch do you have?

Series 1

The Series 1 was released on September 16, 2016, alongside the Series 2. It is distinguishable from the other Apple Watch models by its use of an S1P system in package chip designed by Apple (not to be confused with the S2 system in package used in the Series 2). While the processor performance of an S1P chip is similar to that of its predecessors, it allows for a smaller form factor due to its use of an integrated display driver and apps processor.

The main difference between a Series 1 and earlier model Apple Watch is the inclusion of built-in GPS capabilities. This means that the watch can now track your location without needing to be tethered to your iPhone. The display is also now 50% brighter, making it easier to see in direct sunlight. Finally, theSeries 1 uses a new aluminum alloy that is both stronger and lighter than the material used in earlier models.

Series 2

The Apple Watch Series 2 is the second-generation model of the Apple Watch. It was announced on September 7, 2016, at the Bill Graham Civic Auditorium in San Francisco by Apple CEO Tim Cook, and was released on September 16, 2016. It became available in two case finishes, aluminum and stainless steel, and three band types. Unlike the first generation Apple Watch, the Series 2 cannot be charged with a standard iPhone charger; it requires a higher wattage charger included with the watch.

The watchOS 3 operating system was available for all Apple Watch models at release. The Series 2 watch also features built-in GPS capabilities, allowing users to track their location without having to bring their iPhone along with them. The addition of GPS also allows for more accurate distance and pace measurements when running or cycling without an iPhone. Finally, the Series 2 is 50% brighter than the original Apple Watch, and features a new “S2” dual-core processor which should result in faster app performance compared to its predecessor.

Series 3

The third-generation Apple Watch, and the first to include built-in cellular connectivity. Announced on September 12, 2017, and released on September 22, 2017, it has a similar design to the second-generation model, with the exception of the red dot on the digital crown, used to indicate LTE connectivity on models with that feature. It was succeeded by the fourth-generation model on September 20, 2018.

How to Determine Which Model You Have

There are now three different Apple Watch models on the market: the Series 1, the Series 2, and the new Series 3. If you’re not sure which model you have, there are a few ways to figure it out. First, you can look at the model number on the back of the watch.

Checking the Model Number

The Apple Watch comes in two different sizes – 38mm and 42mm – and three different editions – the regular Apple Watch, the Apple Watch Sport, and the luxury Apple Watch Edition.

To find out which model you have, open the Settings app on your watch and tap General > About. The model number is listed under “Model.”

If you have an original Apple Watch (sometimes referred to as the “Series 0”), it will have a model number of A1553. The 38mm version of this watch has a screen resolution of 272 x 340, while the 42mm version has a resolution of 312 x 390.

The Apple Watch Series 1 and Series 2 come in both 38mm and 42mm sizes, with identical resolutions to their predecessors. The 38mm model has a model number of A1662 or A1757, while the 42mm version is A1661 or A1758.

The Series 3 GPS-only model comes in two sizes as well: 38mm (A1861) and 42mm (A1862). The cellular versions of these watches are A1863 (38mm) and A1864 (42mm).

All watches in the Apple Watch Series 4 line come in 40mm and 44mm sizes. These watches also have slimmer bezels than previous models, so they have slightly larger displays despite having smaller overall footprints. The 40mm Series 4 has a screen resolution of 324 x394, while the 44mm version has a resolution of 368 x 448.

Checking serial number

The quickest way to identify your Apple Watch is by its model number, which is listed in tiny print on the back of the watch case. You can also find the model number in the Settings app on your watch:
-Open the Settings app.
-Tap General > About.
At the bottom of the screen, you see the watch’s model number. If you tap it, you also see the band color and material, as well as other information about your watch.


In conclusion, there are several ways to determine which Apple Watch you have. You can look at the model number on the back of the watch, the size of the watch, the color of the watch, or the type of band that came with the watch. You can also use an Apple Watch identification app to help you determine which watch you have.
