At BaselWorld 2010, together with the launch of new timepieces, Carl F. Bucherer had also presented the company’s “Evolution Technology” concept announced as “Smart SimPlexity.”

“Smart SimPlexity” is the leading Swiss watch brand’s innovative approach to the development of movements, mechanisms and additional functions and the production in the manufacture workshops. The results of this innovative approach include the CFB A1000 and CFB A1003 movements and the functional modules of the three Patravi EvoTec watch models.

The CFB A1003 movement of the Patravi EvoTec Big Date is the first ever reliably functioning peripheral rotor, which offers an unimpeded view of the calibre, in addition to innovative developments such as a patented dynamic shock absorption (DSA) for the rotor and a new fine adjustment system (CDAS), which requires adjustment only once.

A solution has also been found for the switching of the big date. This functions with a moveable finger which is integrated into the relevant ring. This finger makes it possible, when changing the date from the 31st to the 1st of the following month, to change only the disk with the second digit while that controlling the first digit stays still.

The Patravi EvoTec Big Date is a gorgeous device designed for ladies – responding to the growing number of women who demand a high level of mechanical and technical sophistication without wishing to sacrifice the independent, feminine aesthetic appeal of their watch. The large date window and a small seconds window add some extra functionality to the watch.

The CFB A1003 calibre provides the functions of indicating hours, minutes and seconds, as well as that of large date. The case is endowed with a screw-down crown. The watch face is protected by a sapphire crystal with a double-sided anti-glare coating.
