Chronoswiss SkelTec Pitch Black Limited Edition

Inspired by science fiction, the latest Chronoswiss SkelTec collection is taking its open-worked horology into the dark. Matt black parts make an extremely reduced and see-through timepiece with a hand-wound 166-part movement housed in an organically shaped 51-part case.

Presented during Watches and Wonders 2021, this new SkelTec model’s knurled bezel and onion crown, typical Chronoswiss design markers, are, as all 51 parts of the case, coated with black DLC.

An added value for the lugs is that they use the patented Autobloc system for an extremely secure fixture of the band: a leather-lined textile strap with folding clasp, developed exclusively for the SkelTec collection.

The SkelTec Pitch Black features a 45mm diameter case. The minimalistic hand-wound C.304 movement operating at 28,800 vph was designed in the Lucerne atelier and is exclusively used for the SkelTec collection. The first thing you notice is the open screw balance at 6 o’clock, reminiscent of a black hole.

Just below the balance, and at 11 and 1, you will find the triangular bridges that anchor the fundamental parts of the movement, including the balance, the main spring and the halo-like minute ring with white numerals.

The central, soot-black X-shape – achieved with a chrome coating – carries the white-lacquered hands filled in with black Super-LumiNova. The wheels are covered with a dark grey rhodium coating and a circular grain, whereas other parts are sunray brushed.
