I admit it, I have small wrists. I've worn the 42mm (the larger size) of the Apple Watch and I think it looks like the right size for me so I am thinking the 5S will be the best choice (42 also vs 47/51 for the 5/5X) for me. For a watch I would wear most the time and likely even at night the smaller size brings advantages in weight too, any other men thinking to get the 5S? The Garmin site makes such a big deal over the 5S being their new design for women that it gives me pause but I think that many mens watches are 42mm or even smaller in the real world...
