Buy both
No...sorry, on a serious note:
I had the 111 which i sold to my dad, then i bought the 127 with the proceeds. The 111 looks quite big anyway i think yet it is a lovely watch. The 127 looks VERY big, not sure on my wrist size but it looks big, see pic. Everyone at work says, whoah thats a big watch, but they all love it. I prefer now to wear my seamaster under my shirt, and not sticking out
So go for the 127 in my opinion but if your really unsure stick to the smaller 111 they're both gorgeous!
