How to Check What Size Your Apple Watch Is

The Apple Watch comes in two different sizes. For Series 7, it’s 41 and 45mm. The sizes for Watch SE, Series 6, Series 5, and Series 4 are 41 and 44mm. Series 3, Series 2, Series 1, and Apple Watch 1st gen were available in 38 and 42mm casings.

Use the following methods to confirm what size your Apple Watch is:

Method 1- Find Watch Size Via Model Number

The easiest way to find your Apple Watch case size is its model number. You can check the size by matching your model number in the chart given above. Or you can visit the Apple support page linked above and look for your model number.

Method 2- Find Apple Watch Size from Case

Alternatively, you can check the engraving on the Apple Watch rear, which shows information about the Series, GPS or Cellular, and case size.

For example, here, the rear of my Apple Watch reads “Series 7, 45mm,” followed by the mention of “GPS.” This indicates an Apple Watch Series 7 GPS model in 45mm size.

How to Find Your Apple Watch Serial Number or IMEI

So if you want to check the serial number for an Apple Watch that wouldn’t turn on or connect to your iPhone, remove the band (the one towards the Digital Crown). And then, look closely inside the band slot to find your Apple Watch Serial Number.

The above method works for all Apple Watches starting Series 1. If you have Apple Watch 1st Generation, check the back of your watch for the engraved serial number.
