Patek Philippe debuted its Watch Art Grand Exhibition at London's Saatchi Gallery in 2015 and aptly highlighted its artisan's skills with a limited number of special edition pieces offered to its most valued clients. The present example of the much admired reference 5089 was perhaps one of the most targeted and unique offerings displaying in grisaille technique enamel, one of the United Kingdoms most loved and admired institutions, the Palace of Westminster. Adding a finer layer of personalisation for this historical exhibition the outer track of the dial features numerals that are a direct match to those fitted to The Great Clock, "Big Ben".

Part of the London Monuments series, the reference 5089G-041 was accompanied by a further limited series -040 that juxtaposed London's historical sky line with more contemporary architecture of the London Eye and Gherkin. Research shows that of this extremely rare series of handcrafts, the present lot is the first to publicly appear at auction and is both consigned from the original owner and was presented to Phillips' London office double sealed before being removed from its seals for shipping purposes on January 17, 2023. This fact has been attested to by Phillips' General Council with video.

Visible through a sapphire caseback under the discreet hinged caseback, this classic Calatrava cased in white gold houses the ultra-thin self winding caliber 240 micro-rotor movement. Impressive and a rare treasure of artisanal crafts, the present ref. 5089G-041is further enhanced by a full suite of accessories including International Guarantee stamped by the UK retailer Boodles and box. Such masterpieces of artisanal excellence are truly rare and the present watch represents a unique opportunity to acquire one of Patek's finest editions combined with one of the worlds most unique and revered backdrops.

It is the first time this reference appears with the present dial configuration at auction, marking an important moment in auction history.
