Justin Wilson –
At first I was focused on the specifications, but the styling ended up being the deciding factor. The overall finish is clean, and black dial and 40mm case adds just enough visual interest. Customer-service information was useful when I wanted clarification before placing the order. I’m pleased with how it turned out.
