As the first self-winding wristwatch with a date display produced in series by Patek Philippe, this model is in a class of its own.
Two other features underline the significance of this reference, which was introduced in 1961. One is its timeless aesthetic, rooted in a balanced pairing of design elements found in dress watches with the function-driven minimalism of tool watches. The second aspect is the superlative quality of the mechanism. The high-grade movement caliber 27-460M features an 18k gold rotor and the coveted Poinçon de Genève quality mark.
