8.Unique Cushion-shaped Since Button Chronograph in 18k White Gold – $3,637,408
This is the only cushion-shaped mono-pusher chronograph that was made by Patek Philippe in 1928 and was sold in 1931.
The luxury timepiece is believed to be unique because it may be one of those made-to-order watches, one of the few cushion-case chronographs produced by Patek Philippe.
This, however, is the only single button chronograph in white gold that Patek has ever produced.
The luxury timepiece inspires excellence as it has a timeless design fully made out of white gold, spade hands and spplied Breguet-numerals.
Looking past its amazing and rare combination of materials, let us not forget that the wristwatch was manufactured nearly 90 years ago yet is still looks and functions like it just came out of the factory!
