The Ulysse Nardin Blast Tourbillon (Ref. 1723-400/00) is a bold, modern take on high horology, built around the brand’s sharp, architectural “Blast” design language and engineered to showcase its mechanics in full view through a highly skeletonized display. At the heart of the watch is the self-winding Caliber UN-172, featuring a flying tourbillon for increased chronometric stability and visual drama, beating at 2.5Hz (18,000 vph) with an impressive 72-hour power reserve; the movement is made up of 137 components, runs on 25 jewels, and utilizes a silicon escapement for improved efficiency and long-term reliability, delivering a clean time-only layout (hours and minutes) with the tourbillon floating as the focal point of the design.
