mainly the ones for Patek's own events or other limited editons for ADs (similar to Wempe) as well ?
For Patek's own history, you might want to consider additional LEs related to 1) advance research starting with 5250 to 5650 (i.e. the "Terminator"), and 2) the 2005 opening of Patek boutique in China, 2012 opening of Shanghai Maison, 2014 opening of Beijing Maison, and 2015 for the 10th anniversary of Patek in China.
Good luck on your specific journey and let me know if you need help on specific items !
