I currently have a 42mm SS with classic buckle. I like it, but I can't quite get the fit right. Hole #6 is a tiny bit loose, and hole #7 is too tight. Does the leather loop give you the true fine tuning of size that I'm looking for? Also, my wrist is approx. 185mm. Should I get medium or large? The sizing guide makes me think large, but I've read that the large is often way too big. Thanks for the help!
