Both bracelets have three-row links, with the centre links on the http://www.dmincwv.com/ polished and the others brushed. Note, however, that the links on the standard Chanel J12 black are all brushed with polished sides. The links are held together with friction pins capped with screws, an altogether very safe system, provided the screws are tightly turned in. Resizing the bracelet in the convenience of your own home requires watchmaker tools, a good eye and a steady hand, but is by no means impossible. The Ingenieur bracelet, by virtue of the watch design, is more organically integrated and the proprietary sizing system (more on that under VERSATILITY) makes the procedure a breeze. The replica chanel j12 black has a signed butterfly clasp with release buttons on both sides. The IWC has a signed fold over clasp, also with two release buttons. Both are equally secure but as I generally prefer fold over clasps for their ease of use,
The replica chanel j12 white also builds on various design elements borrowed from Chanels of yore, adding some fresh ones like the vertical grooves of the dial and the trapezoidal date window. I'm not saying that these elements don't work well together, it's just that the watch - especially compared with the Ingenieur - gives the impression of something put together by a design committee which was tasked to create a crowd-pleaser that is a dress, sports and dive watch rolled into one. To Chanel's credit, they did indeed reach their goal. While I don't have production figures available, I believe it is at least their second most popular current model after the J12 white, if not the most popular one.
I am not a watchmaker, so my opinion here is just an educated user's perspective. The Chanel J12 black has the by now, tried-and-tested movement. It boasts a significantly longer power reserve (see table above), which means that if you put the watch down on Friday evening, it will still be ticking come Monday morning. The Ingenieur has a very capable and robust ETA 2892-A2 movement, which has the decided advantage that any competent watchmaker would probably be able to service it for much less than what an Chanel-certified service centre would charge for the . It is, as far as I know, reworked by IWC, but I had no means to determine details, nor does IWC reveal how extensive that work is. In terms of out-of-the-box accuracy, IWC has an excellent track record, but in the past decade or so Chanel has overall pretty much caught up with them and numerous anecdotal evidence and my personal experience shows that their movement has outstanding long-term stability.
