I have to agree with mikeoday, the seconds dial is way too small to read. Other than that, looks good.
I noticed in your description, it says the design may blur on smaller watch faces. I find that in order to get the best results across multiple platforms and screen resolutions is to make my graphics projects at 640x640px in Photoshop first. I also add a small 0.5 - 1.0 px gaussian blur to help smooth my edges when scaled down to fit the actual screen.
If I may comment on the logo, I assume it is the logo on the "dim" mode face. I find the less busy I make my logo, the easier it is to adapt it and use it in various formats. Same goes for the font I choose or create. I like to create most of my content, but fonts are a weak spot for me, so I tend to use or modify pre-existing styles to meet my own needs.
