The Operation is controlled by microcontroler.
High contrast transflex LCD’s white segments on black background are used to display the functions.
A six digits display allows the UTC reading.
A four digits display allows the elapsed time reading.
A four digits display allows the chrono function reading.
A three positions selector is used for GPS, INT and SET functions.
