Introduced in 1998, it was the first serially produced perpetual calendar wristwatch with retrograde date to be made by Patek Philippe. It was also the first model since the legendary reference 2497 and 2438-1 to have a sweep centre seconds on a perpetual calendar watch. The model is distinctive for its ‘officier’ style case with elongated lugs with screwed bars and hinged back and display cuvette.
