Patek Philippe Platinum World Time

At the last sale in 2002, an ultrarare Patek Philippe World Time wristwatch sold for the auction price of more than $4 million. The Patek Philippe Platinum World Time was inspired by the inventor of the World Time complication, Mr. Louis Cottier, who had achieved this great feat just four years earlier. It's estimated that since this time the example has risen to an even higher value due to the fact that it is the only one of its kind which was ever built. There have been other models made in its likeness in new generations, some even recently, but none can compare with the original 1939 edition which started the lineage. It bears a much closer look to fully appreciate its magnificence and to understand its significance not only within the Patek Phillippe brand but also within the greater sphere of horology.

Our investigation of this surprising, rare and important model has revealed enough evidence to confirm its authenticity and provide insight into its history.
