Patek Philippe World Time clocks were presented to retailers as in-store displays starting in 2001 to celebrate the release of the ref. 5110. A handful of clocks were also presented or sold to top clients of the company from retailers and distributors. When one of these clocks is offered for sale, collectors often compete at the highest level to obtain the unobtainable. In May 2019, an example brought CHF 56,250 at an auction in Geneva.
