A contemporary sports chronograph with Hublot's assertive design language, this Big Bang Unico pairs a 42mm titanium case with a blue ceramic bezel and skeleton dial for a distinctly technical look. The open dial architecture keeps the mechanics visually central while preserving the model's sharp, layered geometry. An automatic movement drives the chronograph and date. At 42mm by 14.5mm, it wears compact but substantial on the wrist.
