Patek Philippe’s reference 3445 was their first automatic simple calendar waterproof wristwatch, and today is cherished by collectors for its late 20th century modern aesthetic. Released in 1961, it is a model that is as contemporary in the 21st century as it was nearly 60 years ago. Cultural changes following World War II saw a relaxing of social norms with people spending more recreational time outdoors, and gentlemen needed a watch that suited this new lifestyle. The reference 3445 was a highly versatile timepiece able to be worn for dress occasions or casually on the weekends. Over the ensuing years, three series were made with the first fitted with an acrylic crystal, similar to the present watch, the 2nd series made during the late 1970s featuring a higher bezel to accommodate a sapphire crystal, and the 3rd series featuring a sapphire display back. The model was also made with integrated bracelets, and offered with dials in silver, champagne, blue, and later with grey dial with white Roman numerals.

The model stands out for its exceptional movement ticking within. The Patek Philippe caliber 27-460M (“M” for Monodate) is the final evolution of the caliber 12-600, which is widely considered by enthusiasts as one of the finest automatic movements ever made. The present watch is preserved in outstanding overall condition – extremely crisp, hardly worn, and unpolished - and will be a welcome addition to any collection.
