Square Bang Unico reference 821.CI.0170.RX is the black version of the square openworked chronograph. A black bezel, skeleton dial and integrated black rubber strap let the case outline do the work without a second colour competing for attention. The square profile is the feature to buy. Black treatment makes the corners and H-screws more graphic, while the openworked dial keeps the 42mm case from becoming visually heavy. It suits black tailoring, modern sportswear and collectors who already own round chronographs. The case is familiar in size but different in silhouette.

It suits black tailoring, modern sportswear and collectors who already own round chronographs. The case is familiar in size but different in silhouette.
The Square Bang’s straight case edge reframes the skeleton chronograph without changing to a bright material. The black bezel and H-shaped screws mark out the square perimeter; the integrated rubber strap keeps that dark line continuous through the lugs. Buyers who already own a round black chronograph gain a different silhouette rather than a token colour variation.
For a collection already full of round black chronographs, the straight case outline is the actual difference; the openworked dial still carries the familiar Unico language.
The White Ceramic 821.HX.0170.RX Square Bang Unico is the useful nearby choice: White ceramic exposes every square case edge; Black Magic turns the same shape into a more discreet chronograph.
The all-black square case suits a collector who wants a different outline from round chronographs, with the dark treatment keeping the watch easy to pair with everyday clothing.
Before dispatch, our QC team reviews square case alignment, black bezel and skeleton dial surfaces, H-screw seating, chronograph controls, integrated strap fit and clasp engagement.
The square case changes the way the openworked chronograph sits on the wrist; the all-black treatment keeps the outline sharp without adding colour.
The integrated black rubber strap continues the case language and keeps the 42mm watch in a sport-focused role.
Our watch desk can explain differences in case proportion, dial layout and wearing style.
