Patek Philippe 3445/6 Calatrava Automatic Platinum Silver Roman Dial VERY RARE

The Patek Philippe 3445/6 represents a watershed moment in the history of self-winding wristwatches, as it was the manufacturer’s first automatic date model produced in series. Encased in stout and brilliant platinum (very rarely used for this reference), this example is also in impeccable condition with crisp hallmarks. The Calatrava line’s architectural balance is on full display, complemented by svelte casework and understated lugs that tether the piece’s mid-century formalism to contemporary taste. Central to its enduring appeal is the automatic caliber 27-460, lauded for both its mechanical innovation and reliability among discerning collectors. Produced in only a handful of examples, this platinum 3445/6 also features a very uncommon silver dial with black Roman numeral hour markers. For collectors seeking an essential link in Patek Philippe’s lineage, this reference presents a connoisseur’s study in refinement, technical progress, and lasting value. Excellent Condition with European Watch Company leather travel pouch and Patek Philippe service papers dated 2021.
