Jeffrey Toylar –
I spent some time going through the details before settling on this model. The case thickness of 11mm is worth noting alongside the 31mm; together they give a clearer idea of the proportions. Customer-service information was useful when I wanted clarification before deciding. For my purposes, this version makes a lot of sense.
