Which is Size is Right For You?

Both sizes of the Watch 6 offer the same features except for the differences in dimension. Even though the 44mm is bigger than the 40mm, both smartwatches are still compact. The right choice for you depends on your wrist size which will be easier if you have been wearing a watch before now. I would recommend the smaller 40mm for women and individuals with thin wrist while the 44mm will make a better fit for individuals with fat wrist and men.
