What is how do i know what size my apple watch is?

There are a few ways to determine the size of your Apple Watch:

1. Check the back of your Apple Watch for the model number. The model number will indicate the size of your Apple Watch. For instance, if the model number says A1723 or A1861, your Apple Watch is a 38mm size. If the model number says A1860 or A1803, your Apple Watch is a 42mm size.

2. Measure the physical size of your Apple Watch. If you have a ruler or a measuring tape, you can measure the width of your Apple Watch screen. The 38mm Apple Watch has a screen that measures 33.3mm in width, while the 42mm Apple Watch has a screen that measures 35.9mm in width.

3. Check the packaging or receipts from when you purchased your Apple Watch. The size of your Apple Watch should be listed on the packaging or receipt.

4. If you have the Apple Watch on hand, you can also compare it to the size options available on the Apple website or at an Apple Store. The larger size will be noticeably bigger when compared side by side with the smaller size.

By using one or more of these methods, you should be able to easily determine the size of your Apple Watch.
