Patek Philippe 12-120

Probable

Recorded as a near-empty specification. The 12-line manual calibers of this era are documented in specialist literature rather than by Patek, and the catalog states only what it can support. What matters for the reference 96 is not the caliber's specification but the case and movement numbers, which the archive holds together.

Architecture

Small manually wound caliber of the mid-twentieth century, used in the early Calatrava references.

Service practice

A ninety-year-old movement will have been serviced repeatedly, and Patek's own service department has fitted replacement components throughout. Period-correct replacement parts inside a vintage Calatrava are expected and are an originality observation rather than a finding.
