Instinct 2 or 2s for 16 cm wrist - which size

I went 2s with 17cm wrist. Seems a good fit to me and I’m not finding I want a bigger watch at all. But there are only a few mm in it - you could safely do the 2 if the larger screen and battery are important to you. Obviously it would be best to view them side by side in store if you can.

Thanks. Yeah I am inclined to go for the smaller size as I am not used to big watches on my wrist.

16.5 cm wrist here. Instinct 2s fits perfectly. 

I have also a rather small wrist - some 16.5 cm. Have been using the full-size Instinct 1st gen and Instinct 2, 24/24 & 365/365 without any issues or discomfort since almost 5 years. Very light-weigth, I do not even feel I am wearing it, although I originally totally disliked wearing watches. The bigger size is well worth to me, because of the bigger display (my eyes start feeling the age more and more), and because of the longer battery life.
