Patek Philippe ref. 5098P with guilloché dial, circa 2010 The ref. 5098P was launched in 2007 and designed to look almost identical to a Patek Philippe wrist watch from 1917. The hand-engraved, engine-turned dial pays homage to an earlier period when this dial style was more commonly found. The dial of this watch is often described as being a masterpiece of the art of dial making. Only Patek Philippe could produce such a dial in the early 21st century, using the tools and know-how from the late 19th and early 20th century.Complete with box and papers, this example is ready to wear and makes for an exceptional modern addition to one’s Patek Philippe collection.
