Patek Philippe Ref. 5350 R "Advanced Research" Sealed (On Hold)

The second act of Patek Philippe's silicon odyssey. Introduced in 2006 as the direct successor to the 5250, the 5350R takes the Silinvar revolution a step further, pairing the Spiromax hairspring with a silicon escape wheel, deepening the commitment to a movement free from magnetism, oxidation and temperature drift. Housed in a warm rose gold case and limited to just 300 pieces, this example arrives sealed, a remarkable state of preservation for a reference of this significance. Chapter two of the most important modern series Patek Philippe has ever produced.
