THE PROPERTY OF AN IMPORTANT ITALIAN COLLECTOR The following three lots, 122 - 124, consigned by the same important Italian private collector, are from Patek Philippe's "Advance Research" series. All three watches are fresh to the market, in excellent overall condition and with original certificates and boxes. Patek Philippe's Advanced Research department is dedicated to the research of new materials and components for watches. The department has achieved wide recognition for its efforts over the years and attracted much attention for innovative watch parts that contribute to improved rate accuracy and reliability. The creation of silicon (si), or silicium in French, for use in watches has been one of the department's most significant contributions to watchmaking. Patek Philippe used the technique to incorporate it in the making of watch components. New developments based on the use of silicium or Silinvar as Patek Philippe likes to call it are the following: - 2005: Silinvar escape wheel, which does not require lubrication - 2006: Concentrically breathing flat Spiromax balance spring in Silinvar for improved isochronism - 2008: Pulsomax escapement in Silinvar for more efficient power transmission The introduction and use of each of these new developments can be associated with four special limited edition references. The references are, in year of appearance, corresponding to the announcements of the technological innovations made: - 2005: Reference 5250 in 18K white gold. Made in a limited edition of 100 examples (lot 122) - 2006/2007: Reference 5350 in 18K pink gold. Made in a limited edition of 300 examples (lot 123) - 2008: Reference 5450 in platinum. Made in a limited edition of 300 examples (lot 124) - 2011/2012: Reference 5550 in platinum. Made in a limited edition of 300 examples.
