CHANEL J12 H2979 Thank you for looking at our watches. This is a J12, neither black nor white. It's a mirror-like silver color made from a titanium and ceramic composite material. I'm not sure if this is true, but I heard that unlike black or white, the titanium content makes it more difficult to process, and it was only produced for one generation. I think it's a summer watch. The unique texture of the material, which stands out in the strong sunlight, makes it clearly different from many other stainless steel watches. It's fresh and open. There's no doubt that CHANEL's design and watchmaking history are the foundation. Although it has been some time since the watch was purchased, it has been overhauled. I took it to a CHANEL store in Tokyo and asked them to replace the second hand. It is in good condition, having only been worn a few times and occasionally looked at and moved. The velour part of the box it came in has been damaged by hydrolysis. I have spare pieces of the bracelet, so I think I can rebuild it into a full bracelet. While it does not come with a guarantee, it does include a detailed statement of the overhaul at an authorized store. thank you.
