Patek Philippe manual winding movements reflect one of the key principles of watch manufacturing: integrating maximum complexity into minimum dimensions to create a case that is exceptionally slim and timelessly elegant. The epitome of fine horological construction, Patek Philippe’s movements are also distinguished by their refined finishes. Includes Patek Philippe box. Excellent condition.
