Apple Watch users may be unsure of which particular Apple Watch they own or how to figure out which one they have. Each of the variety of Apple Watches comes with a model number that specifies the series and edition, as well as a serial number that is custom to the user’s specific product.

Knowing your Apple Watch model is useful when deciding if your watch is compatible with the latest iOS software, certain applications, cellular connectivity, band styles or whether or not you should upgrade to the newest released watch.

If you decide you want to upgrade, you can visit Apple's Store here.

How to find your model number

To identify your Apple Watch, find your model number by opening the Apple Watch app on your phone. Select the ‘My Watch’ tab, then tap General > About.

In this section you can find the number of songs, photos, applications, capacity, storage availability, version and model of your Apple Watch. See ‘Model’, and click it so that it switches between the part number and the model number, which begins with the letter ‘A’.

Below you can read a description of your Apple Watch based on the watch’s model number.

Display

Aside from the model number, you may be able to differentiate your Apple Watch based on the display.

All models in Series 1, 2, 3 GPS and 3 GPS + Cellular come in either 272 x 349 pixels(38mm) or 312 x 390 pixels (42mm). However, the newer series are a bit brighter than the Series 1 Apple Watches due to a second generation OLED and an increase in Force Touch nits.

Series 1 models contain an OLED Retina display with Force Touch at 450 nits. Series 2, Series 3 GPS and Series 3 GPS + Cellular have second-generation OLED Retina display with Force Touch at 1,000 nits, which makes these models 2x brighter than the Series 1 models.

In addition to Retina Display, Series 2, Series 3 GPS and Series 3 GPS + Cellular watches are waterproof up to 50m, whereas Series 1 models are only splash-resistant.

Lastly, Apple differentiated its latest Series 3 GPS + Cellular watch by marking the winder red.

Power

Series 1, Series 2, Series 3 GPS and Series 3 GPS + Cellular watches all have a built-in rechargeable lithium-ion battery and magnetic charging cable.

Series 2, Series 3 GPS and Series 3 GPS GPS + Cellular come with a USB power adapter that distinguishes them from Series 1 watches.

All Apple Watch models are marketed to last up to 18 hours after an overnight charge. However, battery life varies according to use, configuration and other factors, evident in Macworld’s comparison of Series 2 and first-generation models.

Storage

Apple Watch Series 1, 2 and 3 GPS have a capacity of 8GB, which can be used to store photos, apps, and texts among the built-in features of each model (see here for a complete comparison and list of features).

Apple Series 3 GPS + Cellular is the first and only of the collections to offer models with 16GB capacity. If you’re Apple Watch has 16GB capacity, there’s a 100% chance you have the Series 3 GPS + Cellular model!

To access your storage capacity, go to General > About in the ‘My Watch’ tab. Here you will be able to see whether your Apple Watch has an 8GB or 16GB capacity and how much of that capacity you are free to utilize.

Cellular Connectivity

The ability to connect to 4G LTE and UMTS is a feature only available with the new Series 3 GPS + Cellular model, which was launched alongside new iPhones andApple TV 4K.

The Series 3 GPS + Cellular Apple Watch requires an iPhone 6 with iOS 11 or later and watchOS 4. The Apple Watch and iPhone service provider must be the same. See if your carrier provider is compatible with the Series 3 GPS + Cellular watch here.
