Patek Philippe

.. still uses Enamel material for their moon phase ?? If NOT, which model was the last to receive such method ? or it is still on going ? Thanks in advance.

such as 5078 5116R

..... I am referring to the Blue Moonphase with the Golden stars on perpetual calendar watches. My understanding, the " blue " is enamel, but not sure if Patek still makes that blue or its finished ? ...
