I have a Gen1 stainless & love it. I would lean toward Aluminum over darker - but that's me.
Thanks. I'd love the stainless, but it's not available without cellular or the red dot I don't like very much. Stainless also takes it from $429 to $799 here in Canada. Decisions, decisions...
Honestly, after ordering three extra leather bands I could really have just ordered whatever version I wanted, but I thought the leather straps were beautiful and might outlive an upgrade.
The lugs on the Coach straps appear to be black, which is what made me think Space Grey might be better. I want to be able to wear the watch to work (in a formal corporate environment) and the flatter grey with dark attachment pieces may not look as dressy. I think they look good with the stainless though.
