Mine is the XL while I’ve got relatively small wrists My wrist (just measured it actually never done that other tgat at tailor) is 18 cm The XL is bit large and ine size smaller probably would be better fit
For a Santos i go to a store to fit different sizes. I decided to not want too big anymore , and 42mm is the max. So i think a large will be good, the looks on my wrist and fit. Thank you for the information.
This watch was a gift (well officially I traded it against a 13 year old ladies set of golf clubs value € 150 with a good friend of mine) If I had bought it from an AD I would have selected one size smaller
