Breitling reasserts its horological mastery by launching a “world time” chronograph equipped with a new caliber entirely developed and produced in-house. Thanks to its double disk, the Transocean Chronograph Unitime simultaneously and constantly indicates the time in all 24 timezones. An innovative system based on a patented mechanism enables the user, when changing timezone, to adjust all the indications in one smooth and easy move by simply turning the crown. An exceptional new instrument makes its grand entry into the world of exclusive fine mechanisms.In creating Caliber 01, the Breitling engineers devised the world's best chronograph movement. In developing the new Caliber 05, based on the same high-performance architecture, they have also reinvented the world time mechanism by equipping it with an adjustment system boasting unprecedented user friendliness. The Transocean Chronograph Unitime features two mobile disks: a 24-hour disk and a disk bearing the names of 24 cities representing the world's 24 timezones. The time shown by the central hands corresponds to that of the timezone displayed at 12 o'clock. The city disk also bears indications serving to take account of “summer” or daylight saving time (DST).When the user changes timezone, he need only pull out the crown and turn it forwards or backwards in one-hour increments in order to correct the hours, the city disk and the 24-hour disk in one smooth move. Meanwhile, the calendar is easily adjusted in both directions to the date corresponding to local time. During these maneuvers, the minute and seconds hands continue turning normally without any loss of precision, and without perturbing any chronograph timing operations in progress.
