There is 5711 of a platinum-based jewelry case that is quietly produced without being listed in the catalog. The dial in the list of current models is a completely different model from all diamonds 5719 / 10G (this case is a WG in the first place).

The part numbers are 5711-111P for sapphire, 112 for ruby, and 113 for emerald. And 110 is a diamond. The number of production is said to be 5 each, and it is a fairly rare model. If anything, it is a model that suits the people of the Middle East, but there is also such a world.

5711 / 111P Blue Sapphire bezel

5711 / 112P Red Ruby bezel

5711 / 113P Green Emerald bezel

5711 / 110P Diamond bezel

Is this really Patek officially making a reference? Some people may think, but this is what they are making. The following image is a white dial of 5711 / 111P. The black dial seems to be more popular. Patek is interesting because it does this.
