The first model is Patek Philippe Nautilus Ref.5740 fake with blue dial. In fact, Nautilus just represents the trend in the world between 1970s to 1980s. Before the quartz crisis, people were more likely to wear mechanical watches (especially high-end mechanical watches), and presented a desire for more breakthrough designs. While the aesthetic change promoted appearance of complicated pillow shaped cases like Nautilus.
The models of Nautilus that I love most is not Ref.5711, instead, it is the stainless steel case copy Patek Philippe Ref.5726, which has the function of moon phase. While no matter which one, you will have to wait for them after ordering.
