At Baselworld 2011, Carl F. Bucherer is presenting an additional model in the successful Patravi EvoTec range, but with a different exterior: the Patravi EvoTec Calendar, with an appealing classic round case. It is also equipped with the CFB A1000 Manufacture caliber with peripheral rotor from Carl F. Bucherer. The CFB A1004 functional module offers a useful indication of the weeks in addition to a big date, day indicator and date indication.
