Gosh, sorry to see so much angst on which size to get! I was lucky that I realized the 42 was too big, got the 38 and it is perfect. But I used the 42 for almost two weeks. I was concerned that the 38 would not be as easy to read, etc.
Actually, I am finding the 38 to be easier and more pleasant to look at/read. I am a senior citizen and some small print is hard for me to read but I have no problem at all with the 38. Maybe because of its more compact size .. not sure what it is but it is just easier to read! (I am a woman, BTW.)
I do think you need to consider your whole body and not just your wrist, if you are going for the best proportion.
Good luck, everyone. I hope you find your perfect, beloved watch!! I love mine so much I could kiss it!! LOL!!!
