The Breitling Transocean Chronograph Unitime combines a chronograph with world time functionality, driven by the proprietary B05 caliber. A double-disk mechanism provides instant access to the time across all 24 time zones, and the crown can be turned in either direction to update the hour hand, city disk, and 24-hour display while simultaneously syncing the date. The 2013 Transocean Chronograph Unitime Pilot variant features a stripped-back, instrumental dial that excludes the globe pattern.
