The Chanel wristwatch division was established in 1987, to coincide with the début presentation of the Première wristwatch. In 1995, wristwatch division presented a second design, the Matelassé.Although the Première and Matelassé wristwatches were successful products, the presentation, in 2000, of the Chanel J12 line of unisex style wristwatches, made of ceramic materials, established Chanel wristwatches as a recognised Chanel marque. To date the J12 line of wristwatches features models in four dial-face sizes: (i) 33mm., (ii) 38mm., (iii) 41mm., and (iv) 42mm.; the available features include the “whirlwind” tourbillon mechanism that counters Earthly gravity; chronographs certified by the Contrôle Officiel Suisse des Chronomètres, and the usual bejewelled versions. In 2008, Chanel S.A. and Audemars Piguet developed the ceramic Chanel AP-3125 clockwork, exclusive to the House of Chanel.
