Patek Philippe has a long history of exquisite and complicated timepieces. Their first serially produced perpetual calendar wristwatches reach back to 1941 when the brand released the reference 1526, followed by other exceptional models like the references 2497 and 2438/1 introduced in 1951 as their first perpetual calendar with center seconds. The reference 3448 released in 1962 was the first self-winding perpetual calendar wristwatch, and was replaced in 1981 by the reference 3450 – their first serially produced perpetual calendar wristwatch with leap year indicator. Patek Philippe introduced the reference 3940 in 1986, replacing the reference 3450, as a more modern, less angular wristwatch considered by many enthusiasts as one of the finest examples of a complicated timepiece with round case and micro-rotor-based automatic movement. Its successor, the reference 5140, was introduced in 2006 and continued to use the prestigious caliber 240Q, however the model was updated with a slightly larger 37mm diameter case, compared to the 36mm of the reference 3940. Reference 5140 also introduced more daring dial colors such as a brown dial fitted on the rose gold version and a metallic blue dial on the platinum edition.

The present wristwatch is in excellent overall condition, offered complete with its Certificate of Origin and fitted presentation box and documentations. The black diamond-set dial stands out from the platinum case while still providing a discreet and charismatic appeal as well as a masculine aesthetic. Patek Philippe’s long line of perpetual calendar wristwatches are classic timepieces - suitable for all seasons and occasions, and this exceptional, hardly worn modern example will surely attract collectors looking for a traditional complicated timepiece that will easily fit under a dress cuff.
