They RG CS is lovely. I can appreciate the feeling that 40mm is too big. I wore mine for years but eventually replaced with a 38mm version. Your Resonance is equally beautiful. Which hand do you typically wind with? I'm a righty but with a Resonance find it easier to wind with my left hand be because of the angle. Also try taking a 30 second break after 20 winds of the crown, then continue. I find when I go slower it's more enjoyable and my hand doesn't tire as quickly. Thanks again for sharing two beauties!!!
