What to know
The Square Bang Unico Titanium ref. 821.NX.0170.RX translates Hublot’s layered Big Bang construction into a 42-millimetre square. Grade-5 titanium controls the mass, while exposed screws, a sapphire dial and the broad rubber strap turn the case into visible engineering.
Inside is the automatic HUB1280 Unico, an integrated column-wheel flyback chronograph with a stated 72-hour power reserve. The open display makes the movement part of the architecture rather than hiding it beneath a conventional dial.
Water resistance is rated to 100 metres. That specification, together with the rubber strap and protected crown, gives the watch genuine sports-watch intent. The result is not a softened dress rectangle but an assertive square built around mechanical depth.
