The SXH1 caliber is a proprietary movement designed by Czapek. It is the first in a family of movements developed specifically for Czapek watches, according to the strictest rules of the watchmaking art. It was conceived in cooperation with Le Locle based company Chronode. This manually wound movement has two barrel springs, ensuring 7 days of power reserve and runs at a rate of 21,600 vibrations per hour, (3 Hertz). It features an annular balance wheel with weights for variable inertia and a Breguet terminal curve balance spring. The balance cock has been finely skeletonized and streamlined to give the whole balance greater transparency. It is finely decorated and remains aesthetically and functionally true to the 1850 original. The architecture remains symmetrical, and the sandblasted finish is a modern interpretation of the ‘satiné frost’ technique used in the 19th Century.
