The TAG Heuer Formula 1 Solargraph (38mm) lands the boldest contrast in the collection: black DLC against vibrant yellow. The opalin black dial is cut by a yellow flange and matching TH-Polylight bezel, white Super-LumiNova hands keep it legible day or night. Powered by the Calibre TH50-00, this limited edition charges from any light source. Two minutes keeps it running all day, a full charge lasts ten months. Born from the 1986 original, rebuilt for now.
