  • Catalogue Essay

    With a manufacturer that strives to only offer the best timepieces in the market, innovation is often the key element that drives the momentum. In 2005, Patek Philippe introduced the Advanced Research department to develop new innovations to improve precision and reliability of a mechanical wristwatch through the experimentation of new materials and micromechanics.

    This new collaboration looked at “new materials”, “new manufacturing technologies” and a “new conceptual fundamental”. Out of this came Silinvar®, a patented mono-crystal silicon. This material was unaffected by temperature change and was very lightweight, and required no lubrication and was corrosion resistant.

    Patek Philippe’s first watch to use this new material was the reference 5250 Annual Calendar Advanced Research with Silinvar® escape wheel limited to 100 pieces launched in 2005. In the following year, the firm released the ref. 5350 Annual Calendar featuring a balance spring made of Silinvar® and was limited to 300 pieces. In 2008, the ref. 5450 Annual Calendar was released this time featuring a Pulsomax® escapement also limited to 300 pieces. Three years later, the first Advanced Research perpetual calendar ref. 5550 was introduced presenting the Oscillomax® ensemble limited to 300 pieces.

    The present Advanced Research Annual Calendar ref. 5350 is the second generation of this series and was presented as a limited production of 300 pieces in pink gold only. The watch is fitted with an upgraded movement that now carries a Silinvar Spiromax balance spring and silicon escape wheel.

    Fresh-to-the-market, the present example Patek Philippe ref. 5350R-001 is the 51st to be identified in the market and is offered in excellent overall condition and is also delivered with a Patek Philippe Extract from the Archives confirming the production of the present example in 2008.
