The case has a diameter of 44 mm and a thickness of 13 mm. It is made of 316L stainless steel and is not easily scratched. THE CROWN The crown is nicely positioned at 4 o clock to avoid digging into your wrist. The bezel feels premium, the way it clicks and feels in your hand, it is all very high end. it is a ceramic bezel and to my eye it can stand toe to toe with the best ceramic bezels on the market. this watch is built for purpose, no excuses. THE DESIGN It is the overall angular design that truly struck a chord with me. The angles on this watch remind me a little bit of the lines on fighter jets and indeed supercars. The watch feels almost sculpted, the sides and lines of the case have visually pleasing angles. A mix between polished and brushed sides make this watch stand out.
