The iconic Patravi TravelTec II is known for its unique addiction of a chronograph with three time zones. A specialty of the TravelTec family, this patented mechanism exclusive to Carl F. Bucherer is integrated into the case and can be admired through a lateral viewing window. The pusher at 10 o’clock adjusts the rotating bezel with 24-hour scale beneath the sapphire crystal: Depending on whether the wearer is traveling west or east, the 24-hour ring can be moved forward or backward in one-hour steps.
The local time is indicated by the hours and minutes hands on a 12-hour basis. The minutes hand moves continuously, while the hours hand can be adjusted forward or backward in one-hour steps. When passing midnight, the date also changes both forward and backward. The second time is indicated by the 24-hour hand and the fixed outer bezel, while the third combines the 24-hour hand with the rotating bezel mentioned above. This unique system equipping the Patravi TravelTec is both a masterpiece of watchmaking art and an immensely useful function for everyday travel. The 24 time zones and associated reference cities are engraved on the base, with Lucerne—the home of Carl F. Bucherer—representing Central European Time (CET).
The Patravi TravelTec II also masters short-time measurements thanks to its highly precise, chronometer-certified caliber CFB 1901.1, which also features a chronograph function for timing sporting events that last anywhere between one second to twelve hours.
And, in 2016, Carl F. Bucherer unveils the Patravi TravelTec II featuring a distinctive 47. 4 mm diameter case in warm rose gold coupled with a case back and pushers in lightweight titanium with a black DLC coating.
