The Breitling Transocean Chronograph Unitime combines a chronograph and a world time feature, using its own caliber B05. With its double disk, this watch makes it easy to see the time in all 24 timezones at a glance, no matter where you are in the world. And when you switch timezones, simply turn the crown forward or backward to instantly adjust the hour hand, city disk, and 24-hour disk – while also changing the date to the local time. The Transocean Chronograph Unitime Pilot was introduced in 2013, featuring a more practical dial without the globe design seen on previous models.
