Breitling Transocean Chronograph Unitime

The Breitling Transocean Unitime (Ref. AB0510U0.A732.152A) is a sophisticated, highly complicated men's world time chronograph. Driven by the in-house Caliber B05 movement, it features an intuitive 24-time-zone dial. It features a patented double-disc system (a 24-hour ring and a city disc). It allows the wearer to see the time in all 24 major time zones at a glance. When crossing time zones, simply turning the crown forward or backward corrects the hour hand, city disc, and 24-hour disc simultaneously, while automatically adjusting the date.
