Isn't that the aluminum space gray?

No that is stainless steel you can tell by how shiny it is. See below that is space gray.

I have an SS (purchased when AW launched), plus an Aluminium Space Grey Nike Watch (purchased last year). These days, I typically work the SS four days a week (at work, with suit) & the Aluminium three days a week (with casual wear). Despite being ultra careful, I have a slight scratch on the face of the Aluminium watch, but the SS has no scratches. In terms of weight, I do not notice any difference between the watches - the SS does feel more substantial, but not 'heavier'.

One rather obscure observation - when wearing the SS watch, I often struggle to get Apple Pay to work with the turnstiles on the London Underground...it takes numerous attempts before the turnstiles will open....but when I wear the Aluminium watch, the turnstiles open as soon as I 'flash' my Watch at the contactless sensor!
 
I have the first stainless steel version (I guess series 0) ... bought with the Milanese loop band ... so cost upwards of $800 or so ... this time around I am going with aluminum ... if Apple made these things where the real upgrade cycle was 5 or so years, then it would be worth it, but with a 2-3 upgrade cycle on these, its just not ... I rather waste my money upgrading phones and iPads than watches ... My wife has an aluminum and is in a wheelchair, she bangs hers around all the time, and is in perfect condition ... my SS had micro scratches all over the body and a small ding in the glass before I got a recent AppleCare replacement ... I dont know if ill sell it or just keep it as it does dress up nicely, but not sure its much different than the aluminum with a dressier band like the Milanese ...
