A new type of chronograph, fitted with two independent mechanisms with which the wearer can a) measure short times up to 60 seconds by the centre hand and b) simultaneously record times of up to 12 hours in seconds, minutes and hours by means of the three registers. All this in an “economical” model. (GROEFLIN - TRANSGLOBE)
