Geektastic:
I collected mine today as well.
It really is something. A lot of the YT reviews I have seen have shown it on people with wrists that must be like twigs in comparison to mine, because it looks just fine when I am wearing it and the reviewers often looked like they had dinner plates strapped to their wrists!
Do you mind if I ask what your wrist measurement is? Mine is 160mm and to be honest it feels like I couldn't go much bigger than my existing 44mm series 6, but I'd be interested in your thoughts as someone who's actually worn an Ultra.
