Catalogue Note
Accompanied by a Patek Philippe Certificate of Origin, an instruction manual and a presentation box.
With the first model, the Ref. 5250, the firm unveiled the Silinvar escape wheel, and the second model, the Ref. 5350, supplemented this innovation with a Spiromax balance spring. Ref. 5450 completed this evolution by the addition of the Silinvar lever, which transfers energy from the escape wheel to the balance wheel, resulting in the highly efficient Pulsomax escapement.
Originally known for its application to information technology, Silinvar is a semiconductor that is significantly lighter than the traditional steel, transmits energy more efficiently and can be shaped more
accurately, making it an ideal material for use in watchmaking.
So that the wearer can admire the complex and cutting-edge Silinvar elements of the movement, all three limited edition technological wonders feature a magnified aperture to the sapphire crystal display
back. To this end, the bridge work and wheel train were also altered slightly for increased visibility.
