Note: Tony's handwritten description and the one in the book are incorrect– it reads 'the minute counter is semi-instantaneous.' This watch was part of Tony Simonin's collection (#463) from the Swiss Watchmaking School. According to Tony, Omega made the movement available to the Watchmaking School in Bienne for the students to finish as their school watch.
