Reference 821.NM.0170.RX is defined by its square 42mm case. Silver-grey and black surfaces frame the openworked chronograph dial, while the textured rubber strap follows the architectural outline and uses a one-click release. The choice is less about adding another color and more about changing the watch’s perimeter: it is for buyers who want the Unico display to occupy a crisp, four-sided frame rather than a familiar round profile.
The 821.NM.0170.RX starts with the case rather than the dial. Its square silver-grey and black frame changes how the openworked dial fills the wrist, and the black ceramic bezel strengthens the four-sided read. The layered center remains important, but the perimeter gives the watch its character.
The round 441.NM.1171.RX is the exact form comparison. It offers a similar 42mm technical presence with a more conventional outline. The Square Bang is for a buyer who wants the corners and straight edges to be part of the styling decision, especially with simple sleeves and clean tailoring.
The square frame changes the visual proportion even at the same stated 42mm size. Straight upper and lower edges give the dial a more architectural setting, while the dark bezel keeps the corners from looking decorative for their own sake. It is a useful distinction for a buyer who finds a round chronograph familiar but wants the watch to establish a stronger outline before the dial details come into view.
The side views make the contrast especially clear. A round case carries the eye around its edge, while the Square Bang sets firm corners before the strap begins. That creates a deliberate transition from watch to wrist and a recognizable presence even when the dial is not the first detail noticed.
The textured black rubber strap supports that architecture. Its patterned surface keeps the broad case from competing with the dial, and the one-click release makes the strap connection worth viewing in the gallery rather than treating it as an afterthought. Together, the square case and restrained strap create a graphic result without needing a bright color accent.
Check the square case corners, black ceramic bezel, openworked dial alignment, chronograph hand reset, pusher spacing and textured strap release. Compare the front image with the side and clasp images in the QC set to confirm that the case lines remain clean from every relevant angle.
