Breitling 78

Caliber 78 is a SuperQuartz movement with alarm function, manufactured by Breitling. Introduced in 2012, it belongs to the 78 caliber family and is known for its temperature-compensated quartz oscillator providing chronometer-grade accuracy. The movement was not produced in-house by Breitling. It was discontinued after a limited production run, primarily featured in Breitling's professional instrument watches from the Navitimer and Chronomat collections of that period.
