Hi! I am looking forward for new AW. I have used series 5 44mm and I was happy with it. I am now reconsidering the new sizes - I understand 42 mm might be better fit for my wrist, but I am tempted more to 46 mm. Wouldn't that be too much?
I have a 16.5cm wrist and felt the 45 was just a bit too big. IME 17cm is probably the cutoff where you could go either way. I'm sure 18 would look totally fine and possibly slightly preferable aesthetically.
