Lot Essay

The present ref. 5065A, fitted with a caliber 324 SC movement confirmed by the Certificate of Origin and the Extract, is the rarest version of the steel Aquanaut, of which only a handful are thought to have been made.

The caliber 324 SC was introduced in 2007 but the Aquanaut reference 5065A was discontinued in 2006, so that this version combining the case of the 5065A with the movement of the 5165A is a hitherto little-known hybrid made intentionally by Patek Philippe.

Manufactured in 2012, six years after the official discontinuation of the model, it is furthermore believed to be the very last ref. 5065A made.

As such, it is a great rarity among modern Patek Philippe watches and extremely interesting for the avid collector.

The Ref. 5065A with Movement Caliber 324 SC Explained
The reference 5065A, launched in 1997, was always fitted with the caliber 315-190 movement stamped with the Geneva seal throughout its production life until the reference was discontinued in 2006.

The caliber 324 SC was introduced in 2007 for the updated reference 5165A, launched at Baselworld that year to mark the 10th anniversary of the Aquanaut.

Therefore, in theory this watch should not exist, however, the conclusion can be drawn that Patek Philippe must have made a very small separate series of ref. 5065A, thought to be up to 10 pieces, around 2012, six years after the reference’s discontinuation, most likely for a special order, using the discontinued reference 5065A cases fitted with the updated caliber 324 SC fitted with the firm's new hallmark of excellence, the Patek Philippe or "PP" seal.

In 2009, Patek Philippe created a new quality benchmark for its mechanical timepieces: the Patek Philippe Seal. This new emblem of horological excellence goes beyond any existing standards of the Swiss watch industry. Uniquely, the Patek Philippe Seal applies to the completely assembled watch as delivered to its owner. In conjunction with these standards, the Seal represents a commitment to lifelong servicing and restoration for all timepieces created by the firm since 1839.
