Patek Philippe annual calendar module (Quantième Annuel)
Identity
A caliber is three separate things and this reference keeps them apart: the construction, the names it is sold under, and the article a brand actually bought. A watch model points at an execution — never at a bare construction — which is why “same caliber” is almost never a complete answer.
No designation is recorded for this design yet.
No source in this corpus states which grade any Patek Philippe annual calendar module (Quantième Annuel) was bought at. That unknown is stored as a real row rather than left blank, so it can be counted, filtered and excluded from any comparison that would otherwise assume parity.
