Reference 5270 front and back.
Some may view the task of creating a new Patek Philippe perpetual calendar chronograph as a simple one. It’s not. The new model must be timely and yet timeless. It must be clearly different and clearly better without offending those who worship at the alter of history. Collectors may debate details based on personal preferences, but the 5270 is a worthy heir to the throne.
The new reference 5270 in white gold is priced at $155,700.
