Reference 5270 is the latest iteration of what can be considered the most noteworthy among Patek Philippe lines of wristwatches: the perpetual calendar chronograph with moonphase. While such watches have been made without interruption in series since 1941 - beginning with reference 1518 - the entire line encompasses only five references, each of them considered a landmark model in its own right and fiercely desired by collectors of complicated timepieces.

Launched in 2011, reference 5270 was the first model of the line to be fitted with an in-house movement, as Patek Philippe stopped sourcing ébauches from Nouvelle Lemania in 2010. This strategic decision allows for increased control over the production chain, and it is not a coincidence that it happened around the same time as the introduction of the Patek Philippe seal, the company’s own quality guarantee stamp.

For the first two years, the 5270G was offered with an opaline white dial, but this was discontinued in 2013 for the present iteration. The most striking feature of the present watch is of course its sunburst blue dial. It is interesting to note how Patek Philippe opted for a very subtle sunburst effect: the lines radiating from the center are only apparent under certain lighting conditions.

Offered from the collection of the original owner, this 5720G was purchased in a small town outside Genoa, Italy, near the Italian border with France. It is offered in impeccable overall condition with all of its original accessories, including additional solid caseback. No longer offered in the Patek Philippe catalogue, this is an exciting opportunity to obtain a highly coveted iteration of a modern complicated masterpiece.
