How do I figure out my watch size

If you have an Apple store near you, stop in and try on the various sizes and bands to see which works best for you.

I have smaller wrists, and I still have always gone with the Larger Version and currently have the Ultra. I just like the bigger face and it works well for me.

Keep in mind that you can order a watch that you think will fit and try it at home. Apple has a very easy return process if you are not 100% happy.

If it's paired with an iPhone look at the Watch App on the phone. You should be able to find the Model number and research that.
