Czapek Antarctique Tourbillon - Secret Alloy

The Czapek Antarctique Tourbillon - Secret Alloy has a 40.5 mm steel case, 11.5 mm thick and rated to 50 metres, and a flying tourbillon. In-house self-winding calibre 9 delivers a power reserve of 72 hours with a hand-engraved 5N gold oscillating weight. The grey hand-guilloché dial has a Singularité vortex pattern beneath an anti-reflective sapphire crystal. Luminous hands and indices stand above the surface, with markers attached to the flange.

Sandblasted and hand-bevelled bridges are visible through a see-through case back.
