In 2019, Patek Philippe released the Calatrava Weekly Calendar, Ref. 5212A, which uses Cal. 26-330 S C J SE. This movement is based on Cal. 324 with 92 additional components for a special day/week number complication. Central hands point to concentric days, week numbers, and months around the circumference of the dial.
Cal. 26-330 also features a LIGA-etched nickel-phosphorous gear for the seconds hand with long slotted teeth and an anti-backlash sprint to smooth the movement of the central seconds hand. Additional new features include hacking seconds and a uni-directional automatic winding system. The new movement is also used in the 2019 Nautilus Ref. 5711 as Cal. 26-330 S C with a simple date window and without the complicated weekly calendar function.
