Marc Jenni

Back in 2010, Marc Jenni presented for the first time his Prologue P01 watch at Baselworld. The “Prologue” is equipped with a black ring that rotates around the entire watch case. All three basic functions of a normal crown-function are easily accessible by the selector located on the case at four o’clock. Pure and authentic lines, aesthetic simplicity and mechanical ingenuity; this is how the “Prologue” has been described since its appearance.
