The sporty Chanel J12 Moonphase (ref. H3406) was first presented at Baselworld 2013 trade show. It took them less than six months to start selling the piece in select stores and exclusive boutiques around the world.
The 2011 Chanel J-12 Chromatic (ref. H2566) is presented in a new (or, rather, previously not employed as a material of choice by other watchmaking or jewelry brands) form of ceramic. Probably based on titanium carbide, it looks more like high-polished metal and is way more attractive than those glossy, plasticky timekeepers made using different versions of the extremely robust (albeit easy to shatter) material that was popularized by Rado decades ago.
