Legendary automatic chronograph movement with central chronograph minute hand, used by Sinn in their most iconic vintage models including the EZM 1 (no subdials), Model 140 'Space Chronograph', and Model 142. The distinctive four-handed center layout (hour, minute, chrono seconds, chrono minutes) made timing extremely easy to read. Features 12-hour counter at 6:00, small seconds at 9:00, and 24-hour subdial at 12:00. Production ceased in 2002, leading Sinn to develop the SZ01 as a successor. Constructed with stamped steel and delrin plastic parts, prioritizing functionality over decoration.
