The Patravi TravelTec FourX is the newest version of the Patravi collection by Carl F. Bucherer. One of the coolest functions of this watch is the ability to show three time zones simultaneously. The third time zone can be set using a single push-button mechanism for which a patent is pending.
The watch uses an exotic blend of palladium, titanium, ceramics and rubber. The case is nicely sized at 46.6 mm in diameter and 15.5 mm thick. The movement is an automatic Caliber 1901.1 with 39 jewels and a 42 hour power reserve. What really makes this watch so special and distinguishes it from other TravelTec models, is the skeleton dial. Interestingly, it has a small window inlaid in the side of the case that allows you to view the TravelTec mechanism.
