Chanel J12 Tourbillion

The J12 Tourbillon is the world’s first grand complication in ceramic. The movement plate is carved in hi-tech ceramic (white or black) that is emblematic of the J12 collection. The plate is visible from the back and the jewels are rubies for the black plate and sapphires for the white plate. The bezel and middle of the case are in white gold.
The upper bridge of the tourbillon cage is carved in optical glass and engraved with the inscription ‘Tourbillon J12’. It makes one rotation per minute. The dial of the watch has been ‘purified’ in order to better emphasize the value of this watch creation. The brand expects to produce twelve models in black and twelve in white.
