Patek Philippe Calatrava 3420

The Patek Philippe Reference 3420 is a notable example of the brand's mid-century production, characterized by its clean lines and focus on horological precision. This reference is recognized for its integration of a robust manual-wind movement within a relatively understated case design, appealing to collectors who value technical merit over overt ornamentation. It represents a period where Patek Philippe continued to refine its approach to classic dress watches, offering a blend of traditional craftsmanship and functional design. This reference typically features an 18k white gold case, measuring 38mm in diameter, which houses the Caliber 215 manual-wind movement. The movement provides a power reserve of 44 hours. The watch is fitted with a sapphire crystal, contributing to its durability and legibility. Water resistance is rated at 30 meters, suitable for everyday wear but not for immersion. The dial is silver, often complemented by a small seconds sub-dial. For collectors, the Reference 3420 holds interest as a representative piece from Patek Philippe's mid-20th century output. Its appeal lies in its classic proportions and the reliability of its in-house movement. Variants of this reference may include different dial configurations or case materials, though the core design language remains consistent. It is a piece that speaks to the brand's enduring commitment to traditional watchmaking principles.
