Anyone else torn between two watches? I'm torn between the 42mm space gray sport for $399 and the 42mm SS with blue leather loop bracelet for $700. I love the look of the "all black" space gray, especially since the space black SS is $1,100. I'm a bit unsure of aluminum body, but also can't fully justify the extra $300 when they essentially perform the same. Anyone else in between two different watches?
