What distinguishes it
Look beyond the reference.
The complete calendar displays day, date and month but requires correction after shorter months. A precision moon phase does not change that calendar logic into an annual or perpetual mechanism.
For the enthusiast
The /2 reference is the anthracite-treated execution shown in the Traditionnelle Complete Calendar Openface. Its 308 components and visible calendar architecture make it a useful example for understanding how displays are arranged beneath a dial.
