The ref. 5131 was released in yellow gold in 2008, followed by white gold in 2009, and pink gold in 2014. The white gold version features a map of Europe, Africa and Asia. It is believed that only two enamelists made these miniature works of art for Patek Philippe and each watch is slightly different. As a useful complication for travel showing the time in 24 timezones at a glance, this exceptional reference is a staple in many important Patek Philippe collections. Approximately 150-200 examples of the ref. 5131G were produced.
