This is a one-of-a-kind Calatrava Pilot Travel Time Ref. 5524T-010, the “T” standing for titanium. Titanium Pateks are extremely rare, and therefore often worth even more than their steel or precious metal counterparts.
Even though this is far less complicated than the titanium Patek Minute Repeater that was donated by Patek Philippe for Only Watch 2017, and generated over six million dollars for charity, this one should also command an enormous sum. (Ref. 5524T-010)
The case features a unique brushed finish (as opposed to polished on the standard white or rose gold versions). The dial is also unique with a gray finish and a manually executed vertical satin-brushed surface.
“Children Action 2018” is engraved on the caseback and the watch comes with a vintage black calfskin leather strap with contrast stitching.
The auction will take place in October 2018 at the Four Seasons Hotel in Geneva. The proceeds from the *Christie’s* auction will go to Genevan charity Children Action.
