hi, I've been looking at getting the 43mm black/rose gold Carrera, car2014.ba0799 for a while now, always look at it in the window. My wife has a little diamond aquaracer and we are very happy with it, I have ordered her the diamond cara Delevingne and the AD offered me a good discount as we are still waiting for it and they can't give us an eta. Is the calibre 1887 a good movement, I understand it's not the best out there, but I guess I just don't want to buy it and find out something later that I wish I knew now. Thanks. Mark.
