This manually-wound movement has two barrel springs and runs at a rate of 21,600 vibrations per hour, which translates to 3 Hertz. It features a power reserve of seven days. The manual beveling finish and the sandblasted bridges create a beautiful and modern look, inspired from the past. The most striking elements remain the open ratchets, with teeth polished in ‘bevel’ and unique to Czapek SXH1. They become its mechanical signature.
