The Square Chrono's stainless steel case has a two-tone look to it with a matte silver face and beveled caseback that actually looks more like a titanium hue due to the bead-blasted PVD textured finish - while sandwiched in-between is a black colored stainless steel body resulting in quite an interesting colorway that works really well. The pieces are joined together seamlessly using with what looks like strong industrial hex screws. It's a well made, high quality piece that can instantly be appreciated from the moment you first pick it up. The fit and finish is unquestionably high, as it should be. 40mm might sound too small, but it's actually much bigger than it sounds due to the square shape of the casing. It's actually larger than the 42mm Apple Watch to give you an example. It fits perfectly on my 7-inch wrist.
