It seems like the consensus is to go with the SS. I have both, a 42mm SS & a 42mm Space gray and I'm totally torn as to which one to sell. I wore the SS for a day and had no issues or problems. At first it did seem a little heavy, but I haven't been a 'watch-wearer' and after a few minutes I didn't even notice it on.
The next day my Space Gray came, and right away I thought it looked really cool. I put it on and felt the difference in weight. The other thing I noticed was after a few hours it seemed like small specks of dust were getting caught between the screen and the casing. I didn't notice this on the SS but it could be because everything shows up on black.
The other thing I noticed was the SG, because of the weight felt 'cheaper' when I used the crown wheel and with general interaction with the face. I tried to compare the two crown movements and the crown on both turned the same but I could feel more of the grooves on the SS.
One more observation...it seemed like my the SG became more sticky with on my wrist. I'm wondering if it has anything to do with the ceramic coating on the SS vs the plastic composite on the SG.
Has anyone else noticed or seen any threads talking about how the ceramic feels vs the composite against your skin?
