The required features included in the Type XX specifications were that the watches had to have a black dial, registers situated at 3 and 9 for constant seconds and a minute recording register, flyback for the chronograph while running and a diameter of approximately 38mm. The Breguet Type XX has become one of the most famous due to the fact they re-issued it as a civilian watch both at the time and as a reproduction more recently. The Matthey-Tissot example of a Type XX is much rarer and is based on the same Valjoux cal.72. The current lot represents a fine example of this military style chronograph.
