The 500-piece Fragment collaboration CBS221B.BA0045, launched in 2025, has a 39 mm alternating brushed and polished steel case with domed glassbox sapphire, screw-down sapphire caseback with engraved numbering, and 100 m water resistance. Its black opalin dial combines a white outer flange with silver tachymeter, a black inner flange with 60-second/minute track, three black opalin sub-dials (minutes at 3, seconds at 6, hours at 9), grey printed indexes with grey Super-LumiNova, rhodium-plated faceted hands with white lume, and a date at 12 o'clock. Powered by the in-house TH20-00 (approx. 80h power reserve, column wheel, vertical clutch, bi-directional winding) with a shield-shaped oscillating weight customised by Fragment, it comes on a seven-row steel bracelet with black PVD central links and a butterfly clasp with safety push-buttons.
