Transocean Chronograph Unitime


Transocean Chronograph Unitime

  • Reference №:


With the Manufacture Caliber B05, the Breitling engineers have reinvented the worldtime mechanism by endowing it with unprecedented user friendliness. When the user changes timezone, simply turning the crown forwards or backwards enables instant correction of the hour hand, the city disk and the 24-hour disk – while automatically adjusting the date to local time. Available in steel or red gold, this extremely stylish model is also a high-performance selfwinding chronograph.
