The epic Asian adventures of 13th-century Venetian merchant traveller Marco Polo inspired some of history's best-known explorers, including Christopher Columbus. During Polo's 24-year-long voyage around Central Asia, he met Kublai Khan, founder of the Yuan Dynasty in China, and wrote a book about his travels, which enlightened Europeans to the mystical allure of the Far East for the first time. Polo's Asian adventures have also inspired Swiss watchmaker Vacheron Constantin - the world's oldest watch manufacturer in continuous operation - to produce a collection of watches that honours the accomplishments of legendary explorers. The Vacheron Constantin Métiers d'Art Marco Polo transposes his voyage onto the enamel dial - an astounding technical achievement. Entirely hand crafted in 18ct yellow gold, it is powered by a calibre 1126 self-winding movement and limited to just 60 pieces.
