The vigorous SXH5.01 automatic calibre is the first to be entirely conceived in-house by Czapek from a blank page. Every part of it has been made with care to detail and with the help of the top Swiss manufacturing partners and craftsmen, la crème de la crème, the magnificent orchestra directed by Czapek in the We Collect Rare People spirit. The microrotor, made of fully recycled platinum, is placed off-centre to allow a plunging view into the mechanism and its exceptional architecture. A free-sprung balance wheel with variable inertia provided by four gold masselotte weights enables the highest level of precision tuning. The gear train is held in place by a series of seven handsome skeletonized bridges. Their original shape is reminiscent of lace, inspired on one side by XIX century pocket watches, and by the very modern Czapek Faubourg de Cracovie chronograph’s rotor. The movement has superlative finishing with six hand chamfered inward angles and drawing of the flanks – the summum of Haute Horlogerie finishing, watchmaking aesthetics at its peak. The SXH5 caliber has a significantly longer autonomy than the average of high-end sports watches (typically between 40-45 hours), of 60 hours practical (and 70 theoretical hours). This movement proves that stringent watchmaking craftsmanship can be further enhanced with a hint of free-floating creativity, as if form were an equal party to function.

Everything you always wanted to know about the SXH5 Caliber* (*but were afraid to ask)
  • Haute-Horology caliber conceived in-house and “from scratch” by the Czapek team
  • Exceptional architecture with 7 bridges cut out like lace allowing a clear view of the finishing (the gear train)
  • Original bridges’ shape inspired by 19th century movements and by Czapek Faubourg de Cracovie chronograph’s rotor
  • Superlative finishes with hand chamfering of 6 inward angles and drawing of the flanks
  • 8.8 Newton mm single barrel loaded by a micro-rotor in certified 100% recycled platinum to free up the view on the movement and let it remain reasonably flat and thin (4.5mm)
  • High autonomy power reserve of 60 hours
  • 100% Swiss made (gold excepted) with a majority of components exclusive to Czapek
  • 8 mg.cm² variable inertia balance wheel to allow precise adjustment and excellent chronometry
  • Powerful movement with an optimal balance of inertia and torque to achieve perfect isochronism and power horse versatility
  • Exclusive calendar positioned at 6 o’clock to stay true to Czapek’s aesthetics based on vertical symmetry
