I was recently in the same situation. I was debating over the Blue and the Silver. The Coaxial is really hard to find "in stock" because it's so popular right now. When my local authorized dealer was finally able to ship them in... I went down there right away. I was fortunate because she had also shipped in the 38mm white face with the rose gold markers. The moment I saw it... I just could not take my eyes off it. It's Beautiful!!!! The rose tinted gold markers are really unique and give it a really classy look... not that the Coaxial wasn't already classy enough. Before I went in I had already half heartedly decided on the Blue face... but I quickly changed my mind once I saw the white AT. What it really comes down to though is which one suits you better. If your deciding between the black and the blue... I would go with the blue. The twirling light refection off the face is really really neat. It like it's saying "LOOK AT ME!!!! LOOK AT ME!!!". As for the size... go with the 38mm. The 35 is too feminine. Good luck!!! I know you'll make the right decision that you won't regret! I had so many doubts but I decided to just stop thinking and take the plunge. Other than just recently getting engaged... I've never been happier. There's something to be said about having a really fine watch on your wrist. You feel really proud. Anyways... enough corny talk. Just BUY IT!!!
