Patek Philippe rare Ref.3569

Patek Philippe "Calatrava 3569" manufactured from 1969 to 1986, with the crown positioned on the back.

The dial decoration has a hand-hammered texture.

The hands and bar indices are coated with blue enamel instead of luminous paint.

This white gold watch does not have a crown on the front; it is attached to the case back.

This is called a "back winder" and is a specification sometimes seen on special dress watches from brands like Cartier.
