Catalogue Note

The accompanying Extract from the Patek Philippe Archives confirms that this wristwatch was manufactured in 1964, left the factory with diamond hour markers and was sold on September 14th the same year.


To the best of our knowledge, the current lot is the only example of reference 3445 in platinum to be certified as having left the Patek Philippe factory with diamond hour markers. In fact, only three other platinum reference 3445 wristwatches are known, all of which have applied baton numerals rather than diamond markers. The case was manufactured by one of Patek Philippe's favourite case makers, Antoine Gerlach, known for making most of the calatrava cases and especially skilled in the production of platinum cases.
