The Portuguese Chrono-Automatic from IWC has been a fan favorite for almost 20 years. This specific model features a rose gold case and a silver dial. It was eventually replaced by the IW3714-80 around 2010. The main difference between the two is the type of gold used for the case - the 3714-02 has a rose gold case while the 3714-80 has a red gold case. Keep in mind, for the 3714-02, the recommended buckle is IWA02466 and the folding clasp is IWA05453.
