Replica Patek Philippe Perpetual Calendar, the perpetual calendar is the height of haute horlogerie, the French term for highest-end watchmaking that includes minute repeaters and tourbillons. Typically, it will take even the most skilled watchmakers over a month to assemble everything necessary to make a perpetual calendar work. The feature requires hundreds of extra gears to keep precise track of the exact date. Some of these gears will only be called into action once every four years. The Patek Philippe 5140 is Patek’s round, traditional perpetual calendar.
