C1 BlackSpider Tourbillon

The C1 BlackSpider is presented in a titanium case and holds a 72-hour power reserve movement. The tourbillon cage is fitted on a sapphire plaque fastened to the mainplate and screenprinted with the concord logo. The movement plate serving as a dial is placed at the very bottom and its eight “legs” embedded in the case radiate an air of powerful determination strangely reminiscent of arachnid predators.
