Watch Review: Breitling’s Transocean Chronograph Unitime

UNIFYING TIME. Breitling’s Transocean Chronograph Unitime features their “world time” chronograph equipped with the brand new Caliber 05, which is developed and produced entirely in-house.

With the new Caliber 05, which is based on the high-performing Caliber 01, Breitling engineers have reinvented the world time mechanism via an adjustment system with impressive user-friendliness. The Transocean Chronograph Unitimes features two mobile disks: a 24-hour disk and a disk bearing the names of 24 cities representing the world’s 24 time zones.

The time shown by the central hands corresponds to that of the time zone displayed at 12 o’clock. When changing time zones, users only need to 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. During these maneuvers, the minute and seconds hands continue turning normally without any loss of precision.
