A:AnswerIf you are asking about the watch, just one size. There are dozens of different clock face options many have larger font but as far as I know only one size watch for Versa 3.
If you are asking about the band, it comes in multiple sizes. In fact it actually comes out of the box with two size bands, one smaller and one larger. I have a larger wrist, and the larger band accommodates me quite well.
A:AnswerIt comes out of the box with two watch band sizes, a smaller, and a larger. I have a larger wrist and the large band fit me well with room to spare. There are also a lot of bands in different sizes available on Amazon. I prefer a nice leather band on Amazon sized right for me for $10.
