Caliber 78

About the Breitling Caliber 78

Two liquid-crystal displays sit above and below the hands and carry the functions: a chronograph, an alarm, a countdown timer, a second time zone and a perpetual calendar, selected and set from the crown. Thermocompensation corrects the quartz oscillator against temperature, holding the movement to a few seconds a year rather than a few a month, which is the accuracy the chronometer certificate requires. The movement is 22 mm across with 7 jewels.

In the library it sits under 22 Chronospace references, including the Chronospace Military of 2012 in black steel, and 15 Airwolf references from the mid-2000s. Cases run from 43.5 mm to 48 mm, with the 48 mm Chronospace at 16 references and the 44 mm Airwolf at 11.

The Caliber 79 is the equivalent movement in the Aerospace, and the B71, Caliber 77 and B74 the three-hand SuperQuartz calibers in the rest of the range.
